The MOST under rated TH-cam tech channel.
Yup, one of the best tech info channels on TH-cam
The cuts to text explanations are surprisingly effective
Yes, thanks to the editor! Also the music during that sequence was nice 🤣
A spell check would be nice.
@@rgorde Try reading the text bits again, except not in binary this time.
I recognize some of those!
I understood all the words and most of the concepts but at the end I was still like "I have no idea what Wendell just tried to teach me."
That's quantum mechanics.
I applaud your courage in defying the algorithm to bring your audience this educational content.
If the universe is a simulation, then the fact that quantum systems collapse to discrete states makes more sense: it's load shedding. That way you can have interesting non-deterministic effects in your simulation, then when a system has been observed, you erase all parts of the system state which haven't been exposed to rest of the simulation to save memory.
"And the light shineth in darkness; and the darkness comprehended it not.".
But then you get only the "Picture" of that system. it's like sucking information deliberately "out of context".
Lol asrock adding a 26 megahertz overclock over a reference clock of 2600 and calling it an overclock and selling it as an OC model. That’s literally a 1% overclock.
Bruh.. its the top 1%
Technically not wrong! 😆😁
I heard that and had to skip back to make sure I didn't mishear. It's almost a marketing negative in my opinion, over just having an overclockable model with no change to base.
And reference 6750x spec is already pushed superhigh
EVGA does it with 50megahertz they all do it and charge $50-100 more for it haha
I think I need to watch this about 20 times to even begin to understand this. Wendell continues to impress me with his intellect.
I was afraid I was the only one with these thoughts. I’m an engineer and thought I would understand this better than I actually did.
For my money, this is your best explanatory video yet. The writing is clear, the pacing is great, and you do an excellent job of switching between explaining the technology and the needs that it is filling.
I look forward to any more of these you do.
Before you can say an answer, you need to know the baseline understanding
Could we for the next episode, use some of that IBM compute time for their quantum processor and run a solution for the typical traveling salesman problem? Something easy and straight forward just to understand how to apply the code and see results. This is something like the typical "Hello World" exercise. I just hear about all the quantum computer theory but haven't seen any practical examples.
I run code on IBM and Rigetti quantum computers regularly. Mine isn't for solving something as applicable as a traveling salesman problem but the way you program is the same. I could totally put together a kind of hello world tutorial together for anyone interested.
@@kennyh1529 level1tech forum exclusive hello world with IBM Wuatum Vomputers.
I do research in applying quantum simulation to high energy physics and it's awesome to see this channel touch on topics near and dear to my wavefunction. Feel free to get in contact if you want more explanations!
Any non-scientific applications theorized yet? Like when standard computers were introduced no one thought we'd all have one, much less in our pockets. I'm curious if/how quantum computing will be used by everyday people. Maybe there'll just be quantum computing services we access as cloud services? Feels a bit like a hammer looking for nails for general consumers
If you don't mind my asking, how much of it do you think is hype vs real? All the ones I have seen have QC kinda tacked on to something otherwise unrelated. I think the one that triggers me most is Quantum ML, it seems to be a gobbledygook of vague terminology. FWIW, I'm a former HEP person.
@@pieterrossouw8596 You can access quantum computers in the cloud today if you want. This is not advertising but I have used AWS Braket, their quantum computing cloud platform, to have students go through quantum computing tutorials in near real-time.
@@Quarky_ Yeah, once you start talking about quantum ML or quantum AI my hype meter goes off the chart. I don't think either of those are good near-term applications that are realizable but I'm willing to be proven wrong. To me, the most obvious and realistic use of near-term quantum hardware is in simulating quantum systems that are otherwise impossible to simulate with a classical computer.
@@pieterrossouw8596 Quantum computing is very unlikely to be used in non-scientific applications or in portable quantum computers in this century. As for everyday people, it might never be used by them. The way computers are used today by ordinary people falls into two categories: 1) hobby and office-type, as to serve the curiosity of people about computers, or as to control, store, process data of other applications; say, control a 3D printer, or calculate your taxes, etc., and 2) entertainment and communication, meaning consuming audio-visual content, playing games, communicating with other people.
None of these two categories seem to be able to charge money or serve ads to the regular user in a quantum computing environment better than in classical computing.
Thanks Autumn for the text explanations! This stuff still boggles my brain 😂
Ever since I found out about the double slit experiment years back I've had a few attempts to just somewhat understand it, but man, quantum physics is something I could never wrap my brain around. I'd get that feeling of trying to understand something I wasn't supposed to... staring into the abyss only for it to stare back at me and grin... spooky stuff. I will say this though, am sure glad a good chunk of humanity is actually getting the hang of figuring it out. Absolutely mind boggling.
check out some of Richard Feynman's lectures the man should have gotten a Nobel prize for his lectures to go with the one he got for the science. the early ones from the 50s are some what dated but for that reason the explanations are much simpler for some one who just wants a general understanding.
@@kevint1910 Thanks man, appreciate it. Will definitely look around now that I opened this can of worms again.
to understand "qubit" for computing u should forget 0 and 1 first
quantum using particle not a silicon transistor, it doesn't works like a switch.
just imagine an analog watch with two clock-hands! how many number combinations did you get?
12-12,12-1,12-2.... etc!
12-6 is a super position
It's just a two-dimensional version and only twelve numbers!
now imagine if it sphere and there were (infinite numbers is available theoretically but for this case i can't even figure out 😂😂)
the sphere is "one-qubit"
one-bit only 2 combination available 1 and 0!
two-bit only gives you 4 combinations
00,01,11,10
qubit basically more combination (it's infinite available if anyone able to figure out) in a single particle.. continuously
computer didn't read a number 1 and 0
1 and 0 just a symbol on and off..
qubit use symbol |1> and |0>
silicon transistor computing recognized the switch combination! on and off
quantum computing recognized electromagnetic fields or a light waves or anything depend on what particle we use.
I didn't know about combinatory but when you explained it I thought to my self this is about "is P=NP". I read about this problem when working on an optimisation that I tried to solve in cs class. Then I was chuffed to see the video's conclusion boil down to that same "is P=NP" point.
super position is not 0 and 1 at once, it is between 0 and 1 in as 3 dimension vector (only direction) and 1 if it collapse to up, and 0 when collapse down. Because we can only read in one axies and if vector is not align it would align with probability depending on degree from each value. But calculation can be done as vector operations (only direction)
Oh, that's interesting.
Technically correct, the best kind of correct, but perhaps even more technically correct to imagine the vectors as having both real and imaginary components one of which is unobservable
@@Level1Techs I bes it on spin of electron, and using magnetic field to check it, which collapse it in one of two value. But there are many types of qbits as why of visualisation, but IMO "0 and 1 at once" is worst of it, because it misleading what happening in reality. But I know is popular example as cat in box, which is misleading because it suggesting hidden variable which currently is not what we think is reality.
Please continue talking about this stuff! I know there has been a lot of bottle necks for QC - too many calculations and we get pretty much nothing but noise, and I know there are some interesting discussions to be had regarding the type of gates that they use (they are pretty wild).
Oh, and I would love to see more In Depth talks about the construction of your kvm switch and other projects. Overall, more level1 videos lol.
I love Level1
I like the fact that Wendell even tried to explain this topic to the monkeys on the internet . 🐒 I just want a miniature Q-computer as an art piece.
Nicely done Wendell and Editor Autumn.
Oh man that ASRock graph at the start comparing 2623MHz to 2600MHz did some *heavy* lifting.
1:48 It's when Antman takes his laptop into the Quantum Realm 😂
Thank you, Editor Autumn! SO HELPFUL for a non-compsci pleb like me to have some low-level plain English translation. THANK YOU!!!
one of your bets videos and very educational, thanks a ton for this.
Thanks for doing this video I find quantum mechanics fascinating and you did as good of a job as anyone explaining it simply.
Funnily enough, that explanation sounds like how the newer AI graphics generation works. It does not create the image. It starts with noise and strips away that noise until it gets to an answer that meets the requirements of the input prompt. Because it starts with just noise, it already has all possible answers. It just has to find it by eliminating all "not " answers.
I'm going to take a quantum computing course next week, so ty for this informative introduction!
Never had an idea of how quantum computers work. Thanks for explaining it!
Thank you very much for making this.
really enjoyed seeing you on moore's law podcast the other day!
And the lesson begins. Thank you. All my respect guv
Let's talk about BBC my friend.
You find me jibbering in the corner trying to wrap my head around quantum computering
Odd timing for me, I have my 5th interview today with quantinuum. It's such an amazing field, I'm so excited for the future.
The first example of on-screen text unnecessarily complicated what was understandable in the video. Another one was just confusing but I appreciate the editor's effort. I would have preferred that those examples were omitted and "polynomial time vs nondeterministic time," were included instead when you referred to P vs NP. Unexplained acronyms might be my biggest pet peeve. I work for a big company where people often use such abbreviations and when I ask the higher-ups - mostly just to tease them - "what does that stand for?' - they don't even know! It really doesn't matter all that much anyway since I rarely understand your marvelous videos anyway. Hoping to learn a little something new each time, I keep watching.
The GPU’s gonna need that Radiator-Heatsink
How many security algorithms commonly used are still not quantum proof?
Ok it knows the answer. How do you input the questions?
Good video, don't be afraid to dive deep those that can follow will
smbc comic did an amazing job of trying to explain this too. Massively great at explaining why qbits aren't both 0 and 1 and why qbits aren't 0 or 1.
As a nearly complete layman, what I got from that comic and your video is that qbits are like having a weighted 100 sided-dice, but you don't know where the weight is or how heavily it will lean towards any die-face and any result of >51 is a 1, any result of
"So what are you using this computational-divination machine for?"
"Well, we made this kickass itinerary!"
A close friend ,a Physicist/Mathematician who has spent much of his career working on CANDU tech for the National Research Council, told me after trying to work with 2 Quantum Compute startups on behalf of the NRC between 2018 and 2022,who are begging the Canadian Gov /Venture Capital groups for more $$,that he started out very enthusiastic and hopeful about it all,but now firmly believes its the latest snake oil,from new Shysters,lots of sizzle,near zero steak. He was privy to more advanced iterations of these machines,1 to 2 'generations' beyond what has been shown on youtube,etc,and is now firmly in the snake oil camp,where I remember back in 2017 to 2019 he was ranting to me about how this would be the biggest thing since gunpowder or indoor plumbing or the 1st integrated circuit of its time.
the bloch diagram helps visualize the qubit. Is ibm making aa qubit out of a 2DEG in some exotic semiconductor?
Touching on how they are programmed would be. Interesting, I think.
please show some simple code that uses q-bits. Perhaps sorting something like dna chains, or decoding some cypher.
I would recommend Shtetl optimized but he has changed his tun and I suspect the reason why is that he got new friends at d wave . The main claim of quantum computing is that there are certain problems that traditional high performance computing has a large amount of variation in the most amount of time it takes to solve but that quantum computers supposedly solve these types of problems in a consistent about of time . This means reportedly certain types of computing tasks or problems can be delegated to a quantum computer but high performance computing when optimized to solve these problems is very seldom beaten by any quantum computer and when it is , it is highly suspect
Great explanation... Autumn!
Thank you for this video. I love the idea of quantum computing. I hope that the people working on this will be able to use this for the good of humanity. I wish I was younger and starting my career when I was still 18. This is a field that I would have loved to study and be able to make a career of it.
@spaz dont think that society exists!
That was pretty intense
thanks Wendell
back to you
@@-........ back back to you
Thank you, Autumn!
If they are used for home media servers will they make recent movies suck less?
Thanks for the video!
(i'm a Feynman fan too. he was a pretty smart guy)
Man does this sounds like the ultimate fit for Monte Carlo type stocastic simulations.
Ibm 433 qubit what can do??
Where is the PDP-11 computer? You only showed the console with a wire running elsewhere?
that pix-elation just has me thinking that you guys are standing around a giant hanging phallus
How much is it to rent some Q cycles?
Quite good video. While you didn't go super in depth on how Quantum Computer works, you did explain potential uses for them.
thumbnail made me laugh!
100% saving this video for later. As a sysadmin who happens to be a sci-fi writer, one of my characters is supposed to have a background in this stuff, and having a simple reference like this on standby is definitely going to be helpful. Other than that, quantum physics is always a FUN time (and nobody's gonna get that reference).
You came to Yonkers? Did you raid Micro Center and Nathan's?
Yep. See muh twitter feed
ive left oc gaming behind many years ago.
since when has asrock been making vidya kards?
Well this is all fine and dandy but what kind of overclocking headroom is there Wendel?
(Running away and hiding)
Thanks 😎🤙🦅
From what you describe, it seems that we humans may actually think like a quantum computer. Obviously we can't instantly crunch huge amount of numbers, but we do collapse to an answer very quickly in the same sense.
Thank you! Cheers from OZ
Came for the explanation. Subscribed for the PDP-11/70 panel. Having once owned an actual PDP-11/70 that's immediate cool points with me. 😀
Can you explain a Turbo encabulator next?
I've been interested in that kind of stuff for a while, but the polarisation filter thing is new to me, which - considering and comparing to the double slit experiment - makes sense, but is mind boggling at the same time.
So wearing two, in 45 degrees rotated polarized sunglasses in front of a PC monitor (which emits polarized light) would mostly eliminate the "screen goes dark" problem. Interesting.
For a good explanation of this the MIT Online lecture series on Quantum Mechanics a really good basic explanation of how this works in the first 3 classes. If you want more in depth the rest of the course is pretty good as well, even the problem sets are useful.
thanks for that a little beyond my comprehension but I think i can get if dove in still great stuff man I'd love to truck around these place with you and the good Doctor lol
I would rewatch this but then I thought about the 432 bits of situations where I wouldn’t understand it again
Next video will be Wendell trying to smash together a ghetto quantum computer and posting the steps on the forum 🤣🤣
I have both understood and not understood this explanation, but you won't know for sure until you ask me.
I thought he was going to say,"This has been a....trip." Maybe another universe. But great video Wondel & team.
#Q: How do I make my Core 2 Quad do the Quantum thing? 😁
In the quantum computing explained video explained me nothing. But that says more about me than quantum computing 🤣
I'm so so so stupid...yet keep it going Wendell, you're really a cool guy with a great Channel
It's like quantum processing is based on accumulation of knowledge. It is a stochastic method?
If nothing else, this video has taught me to be even more worried, than I already was about who will get their hands on this technology, and what they will be using it for.
Like A.I..
My brain hurts. Thanks Wendell.
I need to go back to school to understand this.
finally I understand quantum computing
I hope that Asrock paid a lot for that giant 1 min ad of fluff
Next ... Bio computers please!
Do you remember the joke about the computer that had a nightmare?
- Good morning Computer!
- Good morning Operator!
- How are you feeling today Computer?
- I feel terrible and I'm tired...
- ?!!!
- I had a nightmare.
- How so?
- Well... I was dreaming happy 010110110010101000110101110 etc. and at one point 2 !!!
I think the time has come for old computers to have nightmares 🙂
the polarization of light explanation assumes light is 'blocked'. if you do away with this assumption (and instead posit that the light is instead shifted into a complex domain), many supposed 'proofs' fall flat.
nice video
I like how it seems like Wendell went over this with someone else that didn't know anything about quantum mechanics before making a video and posting here.
God. That PDP looks like it should live on the original Enterprise's conference room table 🥵
What about a problem with no known algorithm. There is a proof that any context-free language that has a grammar, has an SLR0 grammar (Simple Left to Right with 0 lookahead). How do we find that SLR0 grammar using quantum computing?
While IBM is betting the farm on it, China will just buy the farm. If you still have to verify the results with Standard computers, you gain neither time nor energy. And AFAIK, the Energy consumption in Quantum computing is pretty high.
The edit at 5min mark confused me more?... not sure if this helps. Why are we mentioning a calcuate factor? What is calculate?... like... calculate 8 into 1 to make 9?
Regarding optical filters: Wave collapse is sayd to be irreversible, which is kind of a problem since the experiment clearly shows that it's affected multiple times.
Think about that for a second...
Yup… Even with Wendell’s great ability to explain things, quantum mechanics stills makes my brain melt…
Don’t worry, QM melts even the brains of Ph.D.s
th-cam.com/video/OWJCfOvochA/w-d-xo.html
I watched the entire video, and all I can say is I'm glad I'm not a computer teacher... I still don't have a clue how a qbit works.
Quantum mechanics is so wild, it literally defies all common sense but somehow has real practical applications
Very fun video! Nuclear physics PhD here. A few of the things people might be interested in:
First, qubits don't have to be just atoms or particles as Wendel said in the video. They can also be constructed out of quasiparticles (see Microsoft Azure's work on topological qubits).
Secondly, while a 433 qubit system sounds impressive, its actually quite a bit weaker than it sounds. Turns out that qubits are very sensitive, and if they interact with basically anything, they will de-cohere from the rest of the entangled qubits, breaking the computation. To get around this, quantum computations simulate logical qubits out of sets of physical qubits. So if you have 433 physical qubits, you'd actually do a calculation with, say, 27 logical qubits, if each logical qubit is being simulated by 16 physical qubits - 433/16 ~ 27 (if you're interested, look up quantum error correction).
Also, the text suggested that quantum computers "already have the answer" to a problem because of superposition. This is incorrect. The quantum computer can theoretically reach the solution for certain classes of problems faster (in the big-O notation sense, for my programming friends) than classical search, and the way this is done is by constructing problems in such a way that the entangled states of the qubits constructively interfere at the solution, and destructively interfere everywhere else. Qubits are just particles (or quasiparticles), they don't "know" anything, and there's nothing magical about them such that entangled quantum systems just spit out answers to problems like an oracle.
Mad props to Autumn.
1:53 Everything we make exploits the physical properties of the universe.
every computer exploit some property of our universe, what else a computer is going to use for that matter any technology
What people need to know is that a Quantum Computer uses the properties of quantum mechanics to solve certain problems faster than a classical computer. A classical computer can do any work that a Quantum Computer can but on certain tasks a Quantum Computer is better.
@@shephusted2714 I doubt we'll see quantum smart phones anytime soon!
This is definitely true and an important thing to say to anyone getting a little too hyped about quantum computers.
Like quantum superposition I simultaneously learned a lot and nothing watching this.
