- Andris is a computer scientist active in the fields of quantum information theory and quantum computing. His valuable scientific input into quantum computer theory makes him one of the world's leading scientists in this field. Andris has invented several of world's first algorithms for quantum computers, including a method to show that some computing problems are hard to solve even with a quantum computer. He is the first Latvian scientist to receive a grant for further research in quantum computing from the European Research Council -- an organisation that supports Europe's best scientists.
Quantum computers are a radically different approach to computing. They use quantum physics (physical laws that work on the level of individual atoms) to achieve faster computing or more secure data transmission. In this talk, Andris Ambainis describes what quantum computers will be able to do, how they work and why building a quantum computer has become one of central problems in physics.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

I find the extreme awkwardness totally endearing, because it's a constant reminder of his extreme geekiness and love and passion for what he does and what it is going to do for humanity.
hungrytomato It is not awkwardness. Its aspee. If You do more math and engeenering for living You will find out more... why science institution have coded locks.
Not to stop people from coming in, but freaks from runing to the town :)
+hungrytomato He totally reminds me of a guy I met as a student. He talked and laughed and even looked just like this guy. He was Russian and was speaking at a conference at UIUC when he was 20. I later learned that he was a genius. In fact, he found some non-fatal flaws in the wiles proof, but quickly found a way to prove another lemma so the proof could continue. It was pretty cool
In all seriousness, this man would do extremely well in any comedy club with the exact same presentation.
He is an university professor plus the Latvian Russian accent. Don't underestimate this guy.
It's pure Latvian accent. But this guy is indeed brilliant. All great scientists have their weirdnesses. Normal people can't think that far and deep.
Please don't overestimate the IQ of the trolls arornd. This guy is astonishing brilliant and also eloquent.
Marc Humer
brilliant, yes. Eloquent, mmmm not so much
Well, I speak the same language *grin My wife would say you are right *lol
First of all, for the record, he is Latvian Latvian, not that this is very relevant.
Secondly, as I remember him from the university, I was in the first year with him -- while he always had his own way of speaking, I think in this case he possibly sounded a bit stressed out instead.
Finally, while a TEDx presentation is a speech, it is the content of that speech that matters primarily and I would say that there was no problem understanding him, so who cares.
I have to admire the sheer magnificent geek this man is
Gotta respect his confidence. Not being self-conscious about his voice is admirable indeed. If I sounded like that, I'd be afraid I wouldn't be taken seriously. He's made of sterner stuff than me.
Thank you for the overview in the history of quantum computing.
Andris Ambainis, Feynman has nothing on this man, what I'd give just to sit at his feet to learn what is really transpiring in the Quantum world, his simplistic explanations set me far ahead of my past just 20 minutes ago!!!
He has a funny voice, which is not bad at all. Many people have funny voices.
But he also is a really cool dude.
Maybe his high voice will make him recognisable like the robotic voice of prof. Hawking did it for him.
I am Latvian and I am very proud about Ambainis.
Yah this guy is amazing. And honestly the voice makes him enjoyable to listen to. Andris is the certainly the man.
Nice explanation, I'm trying to understand both how quantum computer works and also how quantum mechanics is involved in this. The problem is that on the internet nothing is really precise in this explanation so I'm looking every single thing to get a better idea of it. You helped me a lot! Thanks
I think he's great, he's interesting, engaging, enthusiastic and cute.
He got perfect score in math Olympiad so don't underestimate him... And he is a genius so don't go on his style !!!
mhm i had pretty much the same guy in my class he didn't live in this world his mind was only about mathematics and not even the teacher who had a doktorate in maths could always understand what he was thinking about wtf..
Interesting presentation. Also, one of the few tech talks on TH-cam where few, if any, comments cast judgment about the presenter. Good show.
The voice cracking is strong with this one
love this guy he is so passionate about his hobby. I hope everything works out for him
He could acting as the ultimate troll by making everyone feel awkward
how peculiar that aesthetic considerations can still be at the forefront when a highly relevant transmission is taking place, disputable as it may be.
I know he's not from holland but I keep hearing " I'm from holland! Isn't that weird??" Anyway I love this guys joy for his work very inspiring
Awkward? I'd love to see someone that is criticising him get up and do what he is doing. You can even talk about your favourite subject! But you can't do it can you? Because you have to hide behind a computer screen and try to bring other people below your sad little life, just to make yourself feel a bit bigger and better. Keep going. Hopefully one day you feel bigger and better and you'll have the courage to stop.
and wtf are you doing here then? everyone has the right to have an opinion
These are not opinions. They are abuse. And not even clever abuse.
I thought this was a joke at first... But then I realised that this guy is actually really amazing! Great guy
Great explained it a bit better then before.
Is that way "topological quantum field computing" could be a way to go about this.
If you think this was a strange mathematichan look up Kripke the logician. This was nice, impressed if you last 15 min with Kripke one of our times greatest logician.
¡¡¡Wow!!!! ¡¡¡que tema tan fascinante!!!
His head is so busy somewhere else, thinking a zillion things that talking gets allocated a very small amount of resources, just the minimal amount needed for effective communication, and its for the receiver to filter the "noise" factors...
.
true!
When he started speaking I thought he was playing a character lol. But it was a good presentation, I enjoyed watching and that’s the most important. Props to him
This dude is definitely happier and more productive than anyone commenting.
Including me. We should for sure envy him, let alone listen to what he has to say.
That was one of the funniest things I've ever seen. Thanks :)
Oh I'm loving it
I would give my left arm to have this man as my professor
Very interesting.
yeh... But once you get over the voice... you realize how amazing the guy is...
Have you ever hear about asperger syndrome?
Your AWESOME! Remember that your super position is interchangeable and can be used no matter what state or position it is in. Trying to utilize a two state theory in a multiple state environment. This two dimensional approach can be expanded to three dimensions by creating a cubed cubit chip utilizing multiphasic waveform computations. Stacking your cubits layer by layer until cubed. In this way no matter what position (State) your cubit is in its' opposite is a one or a zero. Think of 360º and then put that into a plotted spherical pattern or matrix. Now you can increase your data output according to the number of plotted positions contained in your sphere in an instant. This would require several plots to be used, intermixed, for record keeping between computations. Think of using a virtual computer program instead of hardware for computational throughput.
I have wondered about using resonant frequencies to control quantum particles. Each quantum particle has its' own specific frequency. Using a vectored frequency output to lock a quantum particles position. Excellent Talk. Thanks, Phil
This is what scares people about blind dates!
He sounds like the 10-year old boy who is dressed in lederhosens on the Toaster Strudels commercial...
it's like angels singing...
The awkward moment when you realize that Jar jar Binks is an amazing quantum computer scientist °_°
There really isn't any disagreement about the term. For everyone, regardless of what interpretation of quantum mechanics they prefer, a true quantum computer is one which can implement universal quantum computation. At the moment there is no algorithm whatsoever (!) which is known or believed to run faster on a quantum annealing machine than on a classical computer. This is not the case at all for universal quantum computers which can factor numbers vastly faster than classical computers.
4:58 he steps back
soothing
He sounds exactly like Dr. Strangelove.
strage voice, but highly intelligent. thanks for the talk
writing computer programs without a computer?!? like in my college days in '88 when we only had a few working workstations for 33 students.
The thing I've noticed about cracking a load of encrypted data with no key is.....there's a god damn fucking lot of motherfucking methods, and that's after I've determined the protocal used
A quantum computer of practically infinite time relative to its computing speed cannot break an encrypted message that follows perfect secrecy.
I can totally imagine him saying: "as you see Mr Bond, I am about to inaugurate a little war..."
My answer to his puzzle, what is the last digit of 17 to the 1000th power? 1.
Richard Hendricks + Latka Gravas
Maybe there is some truth in the acceleration of innovation. I want to believe that by now, 2015, there is some mr Leo Kouwenhoven in Delft (The Netherlands) and his team who dares to say that there WILL be complex quantum based structures in about 10 years from now. I think it is based on the ability of room temperature manipulation of superposition and entanglement in diamond..
+Arnold Van Kampen "Maybe there is some truth in the acceleration of innovation."
Some? It is clearly happening. In the last hundred years we have gained more knowledge than in the entire human history before.
+Arnold Van Kampen Im sorry to bother but are you talking about a computer that uses diamonds and lasers as the memory or not.
+Taxtro lmao before 2000 the idea of a 3d printer would be fucked and i have one on my desk rn
actually he has charisma:)
D-wave's computers aren't general quantum computers, just quantum annealing machines. They can't be used to implement either Shor's algorithm or Grover's algorithm, so they don't really apply to this talk.
7:05
he is the real dr. strangelove!
Real Sheldon Cooper in real life 😃😃😃
Gene Roddenberry would have had this guy on the bridge of the Enterprise.
I wanna cuddle this guy
Holographic projected quantum simulated computing, SHORTCUT? Fast as light. Hmmm?
Quantum computation will not work, it will only remain ink on paper. Because if it would, it should have to destroy the uncertainty principle which is a corner stone of QM. Computation requires repeatable and predictable behavior so as to be able to "count" things. QM postulates that you cannot predict any thing with certainty, all you can get is just some probability distributions.
MDW Uncertainity principle is just a popular bullsh... I numebrs are clear, its result in R is just uncertain.
+MDW it already does work but i wonder if you really mean to point out the practical difficulties due to the impossibility of quantum cloning?
Al Quinn
I do not mean it really. I mean it imaginary.
Our perception is disabled because of very specific evolution. But by all prov quantum cloning works. We just dosent have enough experience in it, we just found it few decades ago after aeons in euklidian space.
+MDW That made no sense whatsoever. O_o
+MDW it will be more than an idea on paper im not sure of it. If you didn't know recently a Nano-Biological Computer has come into play. And it does what a quantum computer would do it can run multiple tasks at once unlike your classical/supercomputers. And when it all boils down to it no one really knows what a quantum computer is. I think its a computer that can create life within its self and run thing that no computer could or a computer that has a really large bit like 1000bit instead of 64bit.
now the 3 or 4 schools of quantum physics argue over what is a "true" quantum computer....mean while the software catches up to the hardware
He's a nerd! I like it!
Here's a challenge for you. Watch the whole thing without smiling. :D
Better let him type on a computer and let it to read out the transcript for him.
yeah the voice...lol..but wow heavy.!!!
This guy is fucking awesome lol
i wouldnt want a quantom computer running my car lol, dont want it to randomly steer my car off a cliff through its strange randomness
Omg he is soo nerdy you can hear it
Bro i couldnt stop laughing when he started speaking
I assure you his brain is light yrs ahead of the average guy
BAZINGA
lol its so hard to listen.
1 ...
Whatever tech they use to make Taylor Swift, et al., sound tolerable, needs to be applied here.
we need whatever the f**k they use to make idiotic comments look tolerable. This guy is lecturing about quantum physics and all you can comment on is his voice? I suggest you go back to watching Jersey shore.
dezent calm down:
ffrf.org/legacy/books/lfif/?t=refute
Oh, get a life, guys, there's an über-geek telling about the damn cutting edge of computing science in TH-cam GeekWeek, and you complain about his voice.
But are you smart enough to understand the irony behind this very post of yours?
I actually don't.
If this guy grew up in the USA he would never have become a scientist because he would have been put into "special" school haha :D
He is not retarded or introvert or otherwose has any disabilities.
For example - introvert people do not come on stage to to TED talks, you dig :)
ironic, funny voice, innovative thinker.
Holy....shit......what the fuck happened to his vocal chords? Lol..
viņs izklausās tik dīvaini
wow, I couldn't stop laughing, even though nothing funny ways said.
HAHAHA me too. I was surely intrigued but laughing the whole time
rude
If you mean a good-natured laugh, then yeah, I did the same thing. : )
His voice!!! Lol jeez it's torturing listening to him.
Is the poor guy going through puberty?
So...this is what happens when stuck in puberty.....
Dude is hitting puberty at 45.
Looks like your puberty haven't started yet.
OK :tumbleweed:
Why does he talk like that?
Can you show me that human consciousness is not grounded in matter particles.
then I will invent a new religion.
his accent is atrocious lol but he does give nice points in funny way. but thats an american thought for u lol
grow up, man.
How is this funny? Look up D-Wave. Serious business is going on here.
This guy is talking about quantum computers as if he knows everything about them, but it is clear to me he doesn't know what he's talking about.
explain pls
To be fair, quantum physics being what it is, nobody does! I'm sure he's far more qualified to speak on the subject than any layman.
