"Superposition is a good thing. You should 'Like' it on Facebook" 10:03 The animation on using Qbits to solve a maze problem. The first time I've ever actually understood how Qbits actually help you to do something useful. Thanks guy!
I'd like to see some references for that as well. How does that account for bond geometries as in Pi bonds? What does that do to molecular orbital theory? How does that explain ionization? I think maybe he's oversimplifying.
What Leo illustrated beautifully was classical machines vs quantum computers with the hand shakes, but what he did not disclose is since we are made of superposition particles, that is was possible to greet everyone in the room simultaneously via teleportation & entanglement methods, brain-to-brain instead of mechanically hand-to-hand, so we are far from the realization our mind & body is capable at least of quantum communication and subtle quantum energy but we limited ourselves and the expression of ourselves only in classical, Newtonian ways. Our thinking will gradually change...
Amazing presentation! One observation: the plants use photosynthesis to produce glicose, the oxigen is a (very important) byproduct. And the plant produce it for themselves not for us. But hey, he is into physics ;-)
CO² /sugarsirupH Changes H-H steps gave a sweets (only from mechanical change of atom structures!) It's only one sweet/honeyfeeling Make no toxin, or throw him away!
Now I am truly convinced and inspired to be a Quantum Computer programmer and use QM for Agriculture Work! Perhaps bi-location from the accounts of great and holy Saints is a mastery of superposition. Thanks, Doc Leo for the leaf example with the superposition notation overlaid on it - that brings home the message.
Very sad, when a society decides that good people can be rejected based on a "lottery". But our society does many sad things. Your speech is easy to understand for beginners. Thank you!
The most important thing for everyone to remember... It's not always the most elaborate explanation to solve problems some times it's the simplest things ....
Awesome video! Loved It! Just should have probably had a better title, e.g "Future Quantum Computing." But over all it was a pretty amazing video! I always enjoy watching physics Ted Talks, keep up the good work!
Let's say there are 1024 possible paths in the labyrinth, which means we need 1024 qubits. This is realized by making a superposition of 10 electrons spins (the big difficulty in quantum computing is to keep this superposition stable because it takes just a little disturbance to destroy this superposition and this difficulty grows fast the greater the number of particles) meaning there are 2^10 (=1024) qubits (not electrons). Although there are also 1024 different combinations of 10 normal bits, we still just need 10 bits for each of these combinations, but when you make a computation with them you consider each combination in a sequence, which takes 1024 steps (or less) instead of 10 (or less). But my question is: at the points in the labyrinth where you can go in two directions, how is the superposition affected?
That one "ball" of a classical computer doesn't so much multiply as it becomes a wave function, according to quantum mechanics. When a quantum computer solves that "maze," i.e. finds the one solution that allows the ball to exit, that's called the collapse of the wave function.
Just think about the number of children who are as brilliant as Leo born all over the world not lucky enough to be able to go on to study at university just because they were born in the wrong place. So much wasted human potential :(
Human science is amazing. Man curiosity is motivation. By the other side, nowadays knowledge it not corrrect because we are sure that tomorrow will grow new theories and knowledges. Updating forever...
A 3rd state in storage is one thing (higher capacity, ...). The other is: Use quantum effects in algorithms to solve problems quicker. I"d like to see the algorithm you want to use to actually solve the maze like you showed in the animation, if you actually made it that far.
Great presentation, but it goes to show how important a decent mic/audio tech can be. Difficult to focus with the pops and breathing that could have easily been suppressed or filtered out
Nicely presented! Vedanta explained nonduality (superposition) many thousands of years back. Vedanta and quantum physics go hand in hand. Many of the founding fathers of quantum physics were experts in Vedanta.
heading in the wrong direction... a qbit ... should be a bit which contains not a 0 or a/and a 1 ... also not any value in between .... but it contains all the possible values ... it could take
Just had a thought that I would like to share>>> I’m thinking harrp was created to listen and record earths magnetic field just like memory on water is taken, then put it down in computer formats and doing that would give them the entire history of everything that has been and gone on earth, they could also decipher it and put it into computer formats and in a readable language, how cool is that one.
Nicely presented. The bigger issue will be to prove a computer is actually a quantum computer exhibiting superposition and entanglement. This is not easy. I think late 2015 D-Wave was able to prove their machines scales N2 rather than N3 using a 1152 qubit Washington processor.
From my work in Antihydrogen fusion I’ve found the oxygen atom to be the switching point between parallel universes/dimensions which is the manipulation of matter to exceed the speed of light and quantum entanglement which includes communications and the transportation of matter between levels of spacetime. The aether field is positive energy that builds a (spacing) between electrons and positrons. All matter is condensed light. Nikola Tesla knew about this. Oxygen is the magnetic connection to the aether field for all matter. Utilizing this technology will develop holographic energy and photon systems and spacetime transportation. You can store unlimited information in a parallel universe including spatial or quantum entangled positions for instant access and delivery. Quantum entanglement movie stadiums and communications systems. Unlimited spacetime to even depopulation of the planet. Antihydrogen fusion or dark matter producing dark energy or spacetime or aether field creates atmospheric sprites releasing atomic oxygen stored in the upper atmosphere and antihelium that collects in the outside of the Van Allen belt protecting the planet from the sun. Force fields!
Always had a problem with qbit being 0 and 1 at the same time. Isn't it more correct to say that a qbit is any state between 0 and 1 and has a probability of collapsing to 0 or 1 when observed.
The shared electron between two atoms in an oxygen molecule does not split itself. It is basically sharing an orbit between the two oxygen molecules. Mathematically we might model it with a probability of being present 50% around an atom in any of the two oxygen atoms. This is not splitting the electron. What am I missing?
I'm not sure there is any practical difference between the two concepts, as something moving INFINITELY FAST would be in all possible states 100% of the time.
CNC Scotland Have you done some research into the double slit experiement, or the delayed choice quantum eraser? Quantum mechanics is inherently probabilistic. It's part of the strange black-box behavior of subatomic particles. There is no explanation for it that makes sense in terms that are understandable in the everyday world we know. "Moving really fast" certainly does not explain the delayed choice quantum eraser, which appears to suggest that subtomic particles might not even exist physically unless their position is knowable by a conscious observer. It also doesn't explain how subatomic particles can tunnel through solid barriers, the frequency of such behavior being predicted with 100% accuracy by the probability distributions of quantum mechanics.
THEN YOU HAVE TO ACCEPT THAT MATTER IS MORE INFORMATIONAL , THAN MATERIAL , AND QUANTUM EFFECT MUST USE SOME KIND OF INFORMATION THAT TELL THE PARTICLES AT TWO DIFFERENT DISTANCES TO BECOME ELECTRONS , OR ACT AS ELECTRONS IN NATURE MAYBE THRU SOME STILL UNKNOWN DUALITY MOTHER PARTICLE OR ENERGY WAVE .
I really liked the link between superposition of electrons to frame the larger discussion of chemistry. I'm a teacher, can you help me answer how best to introduce and discuss superposition with children?
With which classical computers he compares? Like from 40 years ago when there were no parallel computing and no multiple cores in the processors? And what he means by 2 times faster? What about clock speed?
40 years ago I could but vaguely comprehend the language of differential equations like line integrals, vector products, let alone the mathematics they described. But the symbols at 8:05 boggle my "mind." I had no idea how far things had changed. I mean so politely, but to me it looks like language extraterrestrials would use, because it is looks so, well, alien.
This actually isn't all that far off from a typical class in Differential Equations and linear algebra (At the honours level). In Quantum mechanics, they denote abstract vectors by kets. See, if you think about it, a vector is merely an object that obeys basic laws for a vector space (ie, linear combos, addition, blah blah). Once you choose your basis, you can start dealing with components. In Quantum mechanics, you denote the state of a quantum system, by a quantum state vector, for example |Psi>... which is a vector that belongs to the Hilbert space (The quantum mechanical vector space). If you could handle differential equations, and linear algebra, then you would be ready for a first course in Quantum mechanics no problem. They just change up the notation because it makes things significantly cleaner.
To illustrate the "double the power" one qubit was added to a hallroom-sized machine which doesn't make sense in the 1st place. That machine would have been as small as a matchbox if not smaller.
not yet but it will run not only crisis but any game for multiple users, so there might be sites online in the future where you can play powerful games without even using your hardware at all, maybe on VR or your phone or google glasses, same goes for multiple handy powerful applications that can run online.
@@-E-M-M- I am not sure if quantum computers will ever be used to run any games. They are actually good at running some tasks in parallel, but games also need a fast cycle time ("clock rate"), which quantum computers can't provide for the foreseeable future.
Why not have it read each quantum bit by its angular NxS axis rotation divided by maybe 24 points depending on how stable... instead of relying on the 3 spin states?
I don't know too much about too much, but is it possible to use existing technology - such as current power lines, radio and satellite communications, even silicon computing devices with quantum technology and computing? - recycling the tech networks we already have, and implementing a new quantum based system on top ?
with the quantum computer, would it not be better to know you are asking the right questions rather than inputting supposition or preconceived notions of what one believes the problem is. For example, the speaker said we are wreaking the environment and resources. If one was to ask how do we stop this in the form of a question the answer that is easiest to come up with is destroying humans. However, if we were to ask the question is lack of resource availability a problem and can better use improve life on earth we would come up with a completely different answer. Input determines output
Thanks for the talk, .. is there references to the point you made about electrons turning to superposition to find their path in plant leaves? Also how does the electron (in that leaf) determine the end state/goal so that it moves towards it in a quantum sense? Last point, and quite similar to another commenter, has the meaning of super position now changed from from: "being in two states at the same time, but only found in one when measured" to "actually being in two places" as your example of the water molecule? was he trying to water down the meaning (expand it) for the public? and has the previous notion of that, the electron was simply shared between the two atoms to compensation the difference in charge? the last point was argumentative, ..
I have a question. If qbits are present in nature. And they use light as energy, why are we using so much energy to bring a chip in a fluid state? Isn't there a simpler solution?
Great talk I like the examples given, they are understandable analogies that "Make sense" (unlike quantum mechanics) However - for his last hope of being "more careful with our resources on earth" I think the NIKE philosophy will help is much sooner "JUST DO IT" !
OK. How do you then understand ~ in all of these infinite paths, that then will become expressed, exactly which one is relevant? I think this answer is used in typical computing already, and you are searching for Grant funds as needed, as not have chosen veterinary inclination.. ..as described in the talk...
Like the leaf, nature employs quantum computers in many other systems. Our brain employs QC to process information, which gives rise to consciousness, so difficult to explain otherwise.
By Quantifying Against the Masses (Lets Say "Subdue & Multiply") it Tends To Limit the Possibility of Surface Estimation... People Either Force to Leap & Bound Their Way Through the Context or Simply Bound Dreaming Too Much! It is Forever Much Harder to Innovate Apon Pre Existent Infrastructure Unless We Erase the Foul Estimators & Simply Adopt Unicin To the "S-PHERICAL WHEEL". In a Nutshell: Calculus! Fatigue! Variation! i.e "Differentzialrechtung" (My German Spelling Bit Tatty) *Muti Dimensional Shifts *21st Century Real Estate *Roadmaps Towards Counter-Projectory Systems *Dual Magnacarta (lol) *Resistent Consumerism Or Even To Highlight "Accesorising More" & "Spoiling Less". Wow! Lets Just Take On Board What Is Naturally Fit To Address our Forward Incline By Tracking the Allocated Use of Our Greater Dependencies Like the Adoption of Response Ability So That Our Children Seize the Intuitive Platform of Natural (Yet Simple) Negotiation of Technical Requisition as Common as the Written Laws That Abide Good Use of Clincal Role/Assessment Engagement for both Leadership & Instruction/s. (Personified/Period). It Might Sound like a Movie or A-Bit Of a DreamScape Yet LIFE IS ALREADY WONDERFUL & ONE BIG CRAZE & MARVEL! *The Greatest Mediation Can be That of Example Setting... *The GREATEST SYNERGY is that Of LAWFUL ABODE! So Yes Fatigue Requires An Abundance of Ease And Our Humanity In These Fields Should be as Primative as Zest (i.e. Counter Projectory & The Negotiation (Wage) of Allocated Good Usages)
We will need the humanities more than ever to guide humanity through that which is brought about by the myriad of disruptive technologies and game changers!
I still don't understand how they can tell one electron apart from another, and how do they know it's superpositioned? How do they know it's not only one electron that's moving so fast (beyond the speed of light maybe?) and we are fooled into seeing it as two different electrons? In the same way that a TV with a certain frame rate can makes wagon wheels look like they are going backward or completely..
Ok i have watched alot of vids that explains in general how a QC works. In general theory everything makes sense. In a normal computer we have 0 and 1 and we use the so called gates to make logic operations like AND, OR, NOT, XOR and so on PLEASE can someone explain how we use the 0 and 1 and both of them in QC to make logic operations?
In Quantum Mechanics the measurement of an electron reduces it to a state of 0 or 1. The "super position" is just how physics interpret the location of the electron as we can predict where it might be and only know once we measure it. The current interpretation in physics is that it can be anywhere all at once aka superposition. During this process of super position we can use the quantum bits to make parallel computation using this state of super positions. However, once we measure it gives us a possible solution aka reduces to a 0 or 1 to lets say a problem we throw at it. It is not guaranteed that the solution that is given will be is correct so they have to use predictive algorithms to lead to a possible correct answer. This is the heart of quantum computer benefits and problems.
When he showed the maze, he said that Quantum computers solve the problem in Parallel. The key word here is Parallel. So, say you have 5 "for loops", the inner loop rely on the outer loop before it can run. How will that run in Parallel?
The electron is actually moving between both bits constantly, but never in both SIMULTANOUSLY. And whenever you require, is always going to be wherever you required, because IT MOVES TOO FAST, and when you make the reading, is here, not there, or there, not here. The same thing with entanglement. But in this case, the connection goes inside, through the Morphogenetic Field and then through billions and billions of connections. Every electron, every proton, every photon, every particle is and can be entangled with every each other particle of the Universe, all through this network of wormholes connections. So, when you have two entangled particles, exchanging information between, is FTL because goes through wormholes, bending the continuum of space-time, and thus, making the connection ALMOST instantaneously, and same as before, when you make a reading or a call, you'll always get what you want, and the other response too. All of this principles can be enlarged to allow supraluminical space travel.
quantum mechanics can do more than a super computer for exemple aura lampe; best view paint, calculated temperature seconde skin, new alliage of neutral metal etc .....
One problem I see is that Quantum computer can decipher cryptography in seconds. I also understand super positioning can build Quantum cryptography that is unbreakable. However, suppose Quantum computer is built by Government or in the wrong hands today, all our sensitive digital communications can be hacked in seconds until entire industries are ready to safeguard their sensitive information with Quantum computing. Logic tells me that there exist a gap / some time period (~t) where all our secured information can be breached.
Two atoms are bound because the binding electron between them is in superposition, orbiting them both at the same time. 10:40 all the possibilities can be checked simultaneously in quantum computer through superposition. Like solving jigsaw puzzle.

I hadn’t realized that covalent chemical bonds are actually due to the superposition of electrons.
I'd like to see some references for that as well. How does that account for bond geometries as in Pi bonds? What does that do to molecular orbital theory? How does that explain ionization? I think maybe he's oversimplifying.
@- Yeah, the planetary model of the atom's been out of fashion for at least 70 years, but it's become a symbol for anything involving atoms.
Ultimately, we have to simplify our models because we cannot actually see atoms yet.
Like that explanations
What Leo illustrated beautifully was classical machines vs quantum computers with the hand shakes, but what he did not disclose is since we are made of superposition particles, that is was possible to greet everyone in the room simultaneously via teleportation & entanglement methods, brain-to-brain instead of mechanically hand-to-hand, so we are far from the realization our mind & body is capable at least of quantum communication and subtle quantum energy but we limited ourselves and the expression of ourselves only in classical, Newtonian ways. Our thinking will gradually change...

I have a question. If qbits are present in nature. And they use light as energy, why are we using so much energy to bring a chip in a fluid state?
Isn't there a simpler solution?

First we have to get all compression ratios of matter. Which is why we don't know much about what kind of matter is there.
OK. How do you then understand ~ in all of these infinite paths, that then will become expressed, exactly which one is relevant? I think this answer is used in typical computing already, and you are searching for Grant funds as needed, as not have chosen veterinary inclination.. ..as described in the talk...
Like the leaf, nature employs quantum computers in many other systems. Our brain employs QC to process information, which gives rise to consciousness, so difficult to explain otherwise.
The Venus project plans to use supercomputers to solve all humanity's problems, including greed.
The labyrint parallel demo results in a different solution than the serial solution....it takes a longer route. Good that it is just a demo🤗
Is it just me or was that lady at 16:04 really looking forward to shaking his hand?
She was fascinated by the knowledge he has as well as his looks 😁
😭💀
By Quantifying Against the Masses (Lets Say "Subdue & Multiply") it Tends To Limit the Possibility of Surface Estimation... People Either Force to Leap & Bound Their Way Through the Context or Simply Bound Dreaming Too Much! It is Forever Much Harder to Innovate Apon Pre Existent Infrastructure Unless We Erase the Foul Estimators & Simply Adopt Unicin To the "S-PHERICAL WHEEL".
In a Nutshell: Calculus! Fatigue! Variation! i.e "Differentzialrechtung" (My German Spelling Bit Tatty)
*Muti Dimensional Shifts
*21st Century Real Estate
*Roadmaps Towards Counter-Projectory Systems
*Dual Magnacarta (lol)
*Resistent Consumerism Or Even To Highlight "Accesorising More" & "Spoiling Less". Wow! Lets Just Take On Board What Is Naturally Fit To Address our Forward Incline By Tracking the Allocated Use of Our Greater Dependencies Like the Adoption of Response Ability So That Our Children Seize the Intuitive Platform of Natural (Yet Simple) Negotiation of Technical Requisition as Common as the Written Laws That Abide Good Use of Clincal Role/Assessment Engagement for both Leadership & Instruction/s. (Personified/Period).
It Might Sound like a Movie or A-Bit Of a DreamScape Yet LIFE IS ALREADY WONDERFUL & ONE BIG CRAZE & MARVEL!
*The Greatest Mediation Can be That of Example Setting...
*The GREATEST SYNERGY is that Of LAWFUL ABODE! So Yes Fatigue Requires An Abundance of Ease And Our Humanity In These Fields Should be as Primative as Zest (i.e. Counter Projectory & The Negotiation (Wage) of Allocated Good Usages)
you know isn't this how classic computers started out and then you see them today imagine in like 80 years from now having quantum mechanic phones
We will need the humanities more than ever to guide humanity through that which is brought about by the myriad of disruptive technologies and game changers!
This is an kind of dark spel is it ?
I still don't understand how they can tell one electron apart from another, and how do they know it's superpositioned? How do they know it's not only one electron that's moving so fast (beyond the speed of light maybe?) and we are fooled into seeing it as two different electrons? In the same way that a TV with a certain frame rate can makes wagon wheels look like they are going backward or completely..
Ok i have watched alot of vids that explains in general how a QC works. In general theory everything makes sense. In a normal computer we have 0 and 1 and we use the so called gates to make logic operations like AND, OR, NOT, XOR and so on PLEASE can someone explain how we use the 0 and 1 and both of them in QC to make logic operations?
In Quantum Mechanics the measurement of an electron reduces it to a state of 0 or 1. The "super position" is just how physics interpret the location of the electron as we can predict where it might be and only know once we measure it. The current interpretation in physics is that it can be anywhere all at once aka superposition. During this process of super position we can use the quantum bits to make parallel computation using this state of super positions. However, once we measure it gives us a possible solution aka reduces to a 0 or 1 to lets say a problem we throw at it. It is not guaranteed that the solution that is given will be is correct so they have to use predictive algorithms to lead to a possible correct answer. This is the heart of quantum computer benefits and problems.
When he showed the maze, he said that Quantum computers solve the problem in Parallel. The key word here is Parallel. So, say you have 5 "for loops", the inner loop rely on the outer loop before it can run. How will that run in Parallel?
I like this guy.
the device at the start is not actualy a computer by turing's specification, just a smart machine
Electron can't be at two places at the same time. It's just that we don't know where it is until it's observed.
I dare him to do the handshake example now :)
I would love to show you how to achieve this goal
The electron is actually moving between both bits constantly, but never in both SIMULTANOUSLY. And whenever you require, is always going to be wherever you required, because IT MOVES TOO FAST, and when you make the reading, is here, not there, or there, not here.
The same thing with entanglement. But in this case, the connection goes inside, through the Morphogenetic Field and then through billions and billions of connections. Every electron, every proton, every photon, every particle is and can be entangled with every each other particle of the Universe, all through this network of wormholes connections. So, when you have two entangled particles, exchanging information between, is FTL because goes through wormholes, bending the continuum of space-time, and thus, making the connection ALMOST instantaneously, and same as before, when you make a reading or a call, you'll always get what you want, and the other response too.
All of this principles can be enlarged to allow supraluminical space travel.
quantum mechanics can do more than a super computer for exemple aura lampe; best view paint, calculated temperature seconde skin, new alliage of neutral metal etc .....
Now we are asking what can we do with them
One problem I see is that Quantum computer can decipher cryptography in seconds. I also understand super positioning can build Quantum cryptography that is unbreakable. However, suppose Quantum computer is built by Government or in the wrong hands today, all our sensitive digital communications can be hacked in seconds until entire industries are ready to safeguard their sensitive information with Quantum computing. Logic tells me that there exist a gap / some time period (~t) where all our secured information can be breached.
CyberNerd1000 Quantum computing evangelists keep saying this, and keep not being able to do it. I wouldn't worry about it.
Two atoms are bound because the binding electron between them is in superposition, orbiting them both at the same time.
10:40 all the possibilities can be checked simultaneously in quantum computer through superposition. Like solving jigsaw puzzle.
