Quantum Computing Day 1: Introduction to Quantum Computing

[insane3alien]

did me good! Had been studying the basic quantum mechanics and encountered fascinating terms related to quantum computing frequently..the three days of these talks left me better..

[mitchTwitch]

so you only have to send 1 bit through the processor and it runs on all your super positioned bits still in ram ?

[lvll138inrs]

how exactly does a quantam computer predict the future?

[peternicholls88]

Already saw this video. Where is the new research?

[DarkAnimeWindSlayer]

Quantum computer will be so powerful that it can predict the future >:3

[harvestsun]

Lol @ the guy at 47:12... He clearly was not paying much attention.

[AlephAlephNull]

@wolvie90 Although I agree explaining to the layman is difficult, the problem is usually when we don't have a deep enough knowledge of the tools we use, for example. An expert in algebra would easily be able to give an explanation that, while not deep, would give your grandma a decent grasp of the concept. QM doesn't have anyone, that I've seen, that can give a layman any idea of what's going on. Hard enough to give understanding to 3rd year phys students.

[Intarabus]

Holy shit! That guy made Google Goggles! haha

[crystalschambers]

*cough* Math *cough cough*

[AdamBMorris]

I wish I could actually read the slides...

[ladangelo202]

too blurry to read which doesn't help

[ladangelo202]

give the correct programming computers will be able to reprogram themselves which is the whole point of a.i. ..... it will increase the rate of productivity and advancement as long as it is controllable or else it just wont be .. anyway this is for computer scientists whom know nothing of quantum mechanics

[fewpeople]

This guy is definately knowledgeable about Quantum Mechanics, but this presentation is pretty terrible. He's got a million equations on a Powerpoint slide and he explains stuff in such a way that you have basically have to be a physicist to know what's going on. His target audience is suppose to be people without background in quantum physics so he should have boil it down to very simple examples that can relate to in real life.

[AlephAlephNull]

@fewpeople The problem with quantum mechanics is that nothing in QM has any "real-life" equivalent. Even the best physicists have "wait, what?" days where what they "understand" one day confuses the next.  Like Feynman said, until you can explain it to a 10-year-old, you don't understand it, and right now nobody really understands QM in such a deep way. We can do the math, but we can't intuit outcomes.

[wolvie90]

@AlephAlephNull It's not only due to the counter intuitive nature of quantum mechanics, I've studied it for about a year now and somthing that strikes me is how terrible lecturers can be. I myself know how incredibly hard it is to explain something like this to someone who hasn't studied it. My grandma asked me about a math exam not too long ago and what it actually was about. I didn't get passed the second sentence until she asked "what is algebra?". Explaining this in laymans terms is not easy

[sexyloser]

Google needs to re-upload these videos in HD.

Not being able to see the equations behind the theory puts a damper on any understanding.

[vality1]

can a qauntom computer really think and make judgement

[hibyewut]

@vality1 as far as I know, no. However, it can just be used to aid the CREATION of better ai.

[DanielxLira]

@vality1 ask your brain :)

[bonfido]

@vality1

No, its just a matter of calculation speed. That is more about AI

[ObserversParadox]

@vality1

A computer is only ever as intelligent as it's creator.

Humans can think and make judgements, so in the future, it is inevitable that computers will have evolved to this level as well.

Fascinating stuff.

[nowaskmehow]

@ObserversParadox yo mama

[DasKrabbe]

@ObserversParadox

"A computer is only ever as intelligent as it's creator."

That's a claim, proof please.

[ObserversParadox]

@DasKrabbe Computers can't be more intelligent then humans because we program them to learn in the same way that we ourselves learn as humans. Therefore their 'virtual capacity for thought' will never exceed our own as long as they are programmed by us. If they were programmed by monkeys, then the computer would only be as intelligent as the monkeys mental capacity allows it to be due to the monkeys limited intelligence. This is not proof, but it is my logic, so think about it yourself.

[DasKrabbe]

@ObserversParadox

Computers clearly already exceed us in several areas, such as chess, which seems to contradict that, no?

[ObserversParadox]

@DasKrabbe

It depends how you define intelligence.

If intelligence is being able to run through each of chess's possible manoeuvres and calculating the risk factor associated with each move.. then you are right.

But what you may have missed is that humans can do this also.. just not as fast.

So if intelligence is the speed at which your brain runs then you are correct. But humans programmed computers to perform all of their functions, so they may be faster, but they only do what we tell them.

[BigMTBrain]

@ObserversParadox - (part 1) "Computers can't be more intelligent then humans", "It depends how you define intelligence." How about if intelligence has to do with awareness of relevant facts in the process of problem solving within a limited amount of time? The recent Jeopardy/Watson challenge (/watch?v=dr7IxQeXr7g) shows that awareness (quick access and assessment of relevant facts) is a great advantage. Speed has A LOT to do with "how intelligent", even among humans, thus TIMED IQ tests..

[BigMTBrain]

@ObserversParadox - (p2) The IBM Blue Brain project (/watch?v=8iDR8Z-e_GU) is working towards emulating a tiny part of a rat's brain. In the US, a full cat's brain. Still others, the human brain. They are all proceeding on a fundamental/modularity approach where any of the fundamentals or module-level components can be experimented with to create many "intelligence" paradigms. These coupled with quantum computers will be well beyond the awareness and intelligence of total humanity in < 100 yrs.

[MrTeaB]

@BigMTBrain but could a quantum computer beat a grandmaster at go?

[BigMTBrain]

@MrTeaB - A Q computer by itself? No. However, imagine a hybrid (binary/quantum) computer 100 years from now. The conventional (binary) side will be literally HUNDREDS OF THOUSANDS of times faster than today's fastest supercomputer. It alone would whip a Go grandmaster silly. I'll even predict that a conventional computer (at least 100 times today's best) will do so using Chess like algorithms in about 10 to 20 years. In 50 to 100 years, hybrids will be playing games beyond human comprehension.

[gossykenji]

Oh my.. please learn speaking englisch without accent... I can't listen to this =/

[coolcheeto]

NO MAMES GUEYYY!!

[Csatrad]

Watching this makes me feel, being smart sux.

[ericharris666]

It's not computer engineering, its all quantum physics. Once you get into Schrodinger cat and Hindenburg uncertainty. you'll start to understand the difficulties and power

[MrBurstingfoam]

@ericharris666 "Hindenburg uncertainty"? Is that where you can't know both the exact position and the exact velocity of an enormous burning German airship?

[NovaN0va]

@MrBurstingfoam Precisely, :P

[T1Brit]

@MrBurstingfoam he he he he ;)

[SalsaTiger83]

@MrBurstingfoam Probably he mixed up Schrodingers Cat there... you know, where you don't know if the airship has blown up yet or not and you can't look because then it goes boom.

[TheLifePerfect]

@MrBurstingfoam I laughed, then I felt bad for laughing.

[s0t0e0f0a0n0]

@MrBurstingfoam Lmfao

[TirianB]

@MrBurstingfoam Lol.

[RuneLancer]

@MrBurstingfoam Naw, that's just how the act of piloting a zepplin invariably destroys information about its energetic state (ie, is it burning or inert?)

[PrinzEugn]

I think he gets to the point around minute 30...

[Da5hiz]

Finally my pre-algebra skills come into use.

[levon333]

Where is it possible to find the presentation slides used in this video?

Thanks in advance.

[DarkShroom]

i've got me a quantum computer right here, it uses the pauli exclusion principle to affect the condutivity of silicon wafers,

i'm thinking of putting together some technoballble in order to get a huge physics grant

[TedDGPoulos]

Think of the underlying law of nature. The way of all things.

Consider its astounding inferences and implications.

The single, underlying law ... of nature! Not merely of physics, chemistry, psychology, biology, etc., but of all known fields of inquiry. The law we can all relate to, identify, understand and apply.

Ask yourself. What is the underlying law of nature?

Delight in the question. Have fun in the process of finding the answer firsthand for yourself.

Google it, as a start.

[jokeistman]

magic, got it.

[Flamesync]

However, I disagree when he said that Quantum computing could be the missing link we need to create a machine with human-level intelligence. First we need a complete understanding of the human brain, etc.

Quantum computing, while a major part, is not THE missing link. We still need much, much more.

[goread41]

perhaps not long after the human brain has been reverse engineered quantum computing will take off from that.

[Flamesync]

I could not agree more.

[bethtubechika]

one of the missin links

[luckinabox]

If you think about it, its impossible to reach Human-level intelligence because it is impossible to determine if something is actually thinking. The only thing you know that is thinking is yourself.

[gobberpooper]

what if every basic thought could be defined mathematically/electromagnetic­ally and then a new form of programming and engineering could derive from that

[Flamesync]

I completely agree when he said that smart synthetic intelligence (such as the type that would help humanity achieve its technological singularity) has a lot to gain from quantum computing.

During the whole first minute I'm like "this guy and I have the same mind"

[MuggsMcGinnis]

At 09:47 into the talk, he shows a slide with the title/subtitle:

"Quantum Mechanics Formalism"/"Quantum Mechanics Cheat Sheet"

I can't read it. Anybody know where to find a copy?

[treeandplant]

part2themovie

will learning mathematics help me in becoming a computer scientist ?please reply

[Nlite10ed1]

yes

[maciejwrotek]

@treeandplant computers are all matematics

[pokerinthbum]

Absolutely Yes!

[Dollarbob]

it is all math you idiot

[notbored12]

If physicists used standard modern mathematical notation instead of obfuscating quantum mechanics using Dirac ket notation, what they are doing would appear a lot more straight-forward, as basically applying linear operators to vectors in a certain vector space, but that would reveal how trivial a lot of current physics "research" is, especially in the area of "quantum computers".

[adulamunda]

I'm interested in what you're saying.

[Phranky]

I used to think I was intelligent but then I was introduced to quantum mechanics.

[sealclubbinfool]

is this a cam of the powerpoint, or a digital recording from the laptop? the quality is really bad

[AbeChang2]

Because physics is the science upon which biology and chemistry are based, and is the science that is the most interesting.

[part2themovie]

i was literally trying to create a topology today: physics > chemistry > biology but it seemed that somewhere i needed to make a bigger table.

[iNick909]

@AbeChang2 this is a very late reply but o well ..... they all rely on each other !

[jtlupo]

can we make a seed.like plant seeds from what we know.like an artificial seed that creates a whole new species of AI or similiar?

[666devilretard666]

lol@teaching software engineers advanced physics.

[666devilretard666]

software "engineers" sit their ass infront of a computer all day and maintain a company's IT infrastructure. Their greatest talent is to learn all the theory needed for advanced computer science and throw it out the window when they enter the work force. A computer scientist explores better or more efficient algorithms to solve a problem far more interesting than being an IT slave. dumbass. quantum physics is advanced relative to classical physics, maybe you should stick to being an IT slave.

[part2themovie]

I'm actually a computer scientist, most engineers have to be computer scientists. IT is something else, more like guys checking your cables and installing Oss. I find it boring and redundant. Electronic engineers make the hardware and software engineers in concert with them create the layers of interface that make up software topology. application programmers then utilize these layers in every field to come out with the software that each has become so reliant upon.

[666devilretard666]

the assertion that most engineers have to computer scientists is wrong. an engineer will make use of software tools to perform whatever task they so choose to desire whether its system simulation or analysis - the act of programming does not make one a 'scientist'. I wouldn't label an engineer working on embedded systems a 'computer scientist', but i would certainly label a person who works on refining image recognition techniques a scientist, although at some point the line does begin to blur.

[matthewcoole]

Software "engineers" as you call them are not maintainers. They are essentially higher level system designers. Granted a software "engineer" will not do much coding however they perform as important job as coders and the other computer scientists who work on developing individual algorithms, they coordinate the design and implementation of a computer system. Without them there would be almost no complex computer systems, at least not any that work correctly (not that many work right anyway) :)

[DarkTrunksGeorgeSim]

I have a part time job as a programmer and my experience has been all but what you say. Every bit of knowledge helps you do your job better. Software Engineers DO work on problems that require an understanding of CS theory such as algorithm design and analysis. You are generalizing the Job of a systems administrator with that of a programmer. A software Engineer can certainly work in both positions.

[cpowell1987]

This is excellent.

[Rocketboy5]

needs to be higher quality

[68EC060]

HMMM a bit complex

[votshtoyalyoobloo]

Actually properly understanding this would be like a whole new life. Really worth anyone's time but it's so hard to keep going with it

[shiftpicker]

lost me at 11:00 :(

[gangman5]

Human level Intelligence?

Ye gods man, have ever SEEN Terminator?

[sonoflipoic]

When [we] see anything it is already old.When the sh#t goes down you we will see terminators =[

[Nanodev]

@gangman5 Skynet is coming soon.

[C4Pieper]

Could it be that the speaker is german?

[sonoflipoic]

Heel bee baahk! =D

[Leobons]

I sink he is

[Schraupe]

based on his name Hartmut and his accent I'd guess so, too ^^

[dlfleming05]

How about this: research what you do not know. Each time you reach an understanding, you are more educated. And ask others. I'm a solar corona physicist but a lot of know our stuff. Just ask.

[hankaaron1961]

25:00 to 28:00 is without a doubt the most profound aspect of Quantum Mechanics.

And the lecturer is not trying to sprout New Age/Mysticism. This is real science!

[fotyafotieva]

)) :))))))))))))))))))

[fotyafotieva]

Жаль не на русском. Тяжело такое воспринимать на англ

[hazonku]

Am I wrong in assuming that he's trying to explain the Heissenburg Uncertainty Principle effects measurement & thus causes infinite outcomes at the quantum level?

[spinhook888]

I'm no good at physics and such but the concept of quantum computers fascinates me greatly.

[pscucailin]

lol @ 6:40. Weird Eastern European making extremely bad joke.

[lorenz0lamas]

he's german, not eastern european

[pravinpatil411]

Im completely lost..Its just too hard. Better leave it to the smart ppl. LOL

[csskid]

so are there actual quantum computers? or are they still theory. . .

[derbigpr500]

They exist....made of 5 or 7 atoms...im not sure...

[adeelfromny]

7 atoms tottal

[alouisos]

How about out a way that biological matter in certain areas works according to quantum principles? You have to find out a way to block the thermal bath that leads to wavefunction collapse....

[darksaga2006]

does anyone know where to find the slides of the speech? The definition here is horrible

[leppy111]

Quantum Mechanics seems to hold it's cards close to it's chest.  "wait you peeked ha,ha now I'm a particle"I love this stuff.

[DarnoQ]

is there a better quality version available somewhere?

[andrewandcindy]

I was fortunate enough to go to a conference on Quantum Computing last summer. I was one of only two undergraduates there, and my mind was totally blown. I strive to understand as much as I can, but I have so much respect for these people who can understand this high-level intersection of physics, computer science, and abstract mathematics.

[tiberux]

you are here because you are smart, this is what's going to make cloud computing come true

[ITvisionary]

All cloud computing is, are a set of hosted services. It's just leasing a service as opposed to hosting your own servers and license purchasing. It's not related to quantum computing at all.

[tiberux]

I think you misunderstood my comment, obviously I wasn't clear... cloud computing requires better parallelized and optimally resource distributed machines to host these services and accommodate the on-demand SAS feature ... and I think here is where quantum computing can come in handy:

Many of the resource management and computing problems can be modelled as attempts to finding global optimal paths as opposed to local optimal paths, current examples of this are NP-complete problems such as TSP.

[tiberux]

ITVisionary...

My argument is that absolute real-time on demand cloud computing will require better resource utilization and optimal allocation to a point where quantum computing based algorithms will be the best viable solution. This the vision I'm trying to convey in my comments.

Thanks

[sergzone]

lol, i'm glad i took calculus only 3 years ago :)

[JUKIO01]

im studying computer engineering right now. i hope one day i will be able to understand this, and maybe even be apart of this. really cool stuff

[EVM3point0]

its funny i like this stuff but i hate math. Physics was fun in high school cuz the math was minimal.

[davidwizard2006]

that is a very good introduction to quantum computer, i buy a book written by issac chuang, i cannot finish the first 4 chapters in more than a whole month, they seems to be so heavily dipped into the hard math, little about how computer is made, or fundamental principal

[Daghead]

This makes my brain feel like an ant's.

[hjaimesc]

Very impressive introduction. I agree his accent is strong but even so the message get it through.

[kbickhaus]

Would be easier if his accent wasnt so strong, and he needs to practice speaking. Very helpful though :)

[spartexx]

wow.. Arnold is very smart xD

[SafetyLight]

I remember when I used to think I was smart. . . Sigh.

[bodomar47]

Wozu brauchen Sie die Sonnenbrille!

[bodomar47]

Ein guter Vortrag Hartmut!

[ronimacarroni]

Arghhh all these gates and 50 minutes of talking and functions and algorithms and stuff, what is this?!

Why can't he be like, these are cubits, now I'm going to turn a magnet on so you can watch them spin, yay

[pav930t]

Can I get white papers from this speaker?

[travisjamesmajor]

good thing he brought his sunglasses

[danmackellar]

wow, my physics proff tried to teach me all this today... good times good times

[EVM3point0]

"tried" how'd it go lol

[pav930t]

Thank you for posting. 10/10.

[PerfectBlindness]

Wow, computer engineers are going to have fun with this one.

[KingKoopa]

I'm on my way to get that degree, and I'm FASCINATED!!

[suffering44]

dats great

[cornskid]

at least a littlt bit anyway

[cornskid]

at least a little bit anyway

[cornskid]

ty you very much for helping me understand

[tommasfoolery]

this german guy is a genius.

[krbrowning]

Why did you take down day 2?

[RabidApe]

MOAR!!!!

lectures 2 and 3 would be AWESOME!!!

thanks, google!

[vecter]

Woops, I meant to vote up, but my mouse slipped and I voted down :(

I agree, MOAR!

[fixeruper]

Pls, where i can get the remaining lectures

[FamilyGuy2277]

It's a shame that 99% of the videos being watched are just funny or look cool, and less than 1% of them are videos you can actually learn something from.

[henrusha]

Says the guy with the name Family Guy

[FamilyGuy2277]

I'm tired of thick people like you that think they are clever.

[nodonnel]

What does this mean: "just funny?" Don't humor and levity have intrinsic value to humanity? I think so, and I believe that even the most serious scientists would agree. Jokes and parodies give us perspective on life and its challenges. They allow us to reflect and move forward.

And I believe that a human creation "looking cool" is the basis for the phenomenon we call 'art.'
