Quantum Computing

[tehdevil6666]

Normal computers started out the size of rooms, even buildings, and have now been shrunk down to the size of you hand, so surely with a bit of time they will find a way to shrink all these omponents down to a level which is can be manufactured on a scale they are today :D

[thisisgrey]

the question is, will I be able to consume more porn in a quantum computer?

[SkrockMusic]

There's so much interesting stuff in this world, It's a free buffet! dig in!

[quangluu96]

the is the first step for quantum computers, just like how the first transistor base computer, a full ROOM size HAHA :D in a few decade of century, this will scale down to mobile XD

[huzanaaier]

4 people are creationists

[navgahs]

if it can break the security, it also possible the quantum computing can make the best security available...we need more people do research on this, and this video might be the first step to the next on...

[TheGuyNamedAnon]

Kinda scary, though. Someone could brute force a password and figure it out in seconds with this.

[DasKrabbe]

@TheGuyNamedAnon

No, no, no... The guy is talking nonsense.

[CrispyHarpi]

Was this filmed at Birmingham Uni?

[Instructinator]

@CrispyHarpi i do'nt know

[DasKrabbe]

Stop sitting in a park and look cool. Go study your subject

[FermiGBM1]

@DasKrabbe Fuck you he has a PhD., show some respect to him for taking the time to make this.

[DasKrabbe]

@FermiGBM1

PhD or no PhD, he is wrong. Maybe he should have spoken to someone who knows the subject beforehand?

Sorry, I just get annoyed when people spread misinformation like this. 

[DasKrabbe]

Christ. TSP is NP hard. Unless I missed a major breakthrough in computer science, we cannot solve this quickly on a quantum computer.

[aceennis1]

@DasKrabbe Quantum computers are a major breakthrough in computer science!!!

[uudo]

The salesman problem: don't they usually use pathfinding algorithms to figure the shortest distance out? I mean, there are quad-, octtrees (cutting down on the calculations immensely), A*. It's no a matter of finding all the possible routes and then figuring out which is the shortest, or is it?

[webmastertool]

What branch of engineering or physics do i have to study to get into quantum computer building and research?

[the1sand1god]

In 20 years from I will look at my computer and look at this video and laugh at it because I would have a quantum computer ^^ cant wait.

[oneillsg111]

This was very well explained. Very, VERY helpful. Thank you very much.

[MyStuff774]

Damn, this is too awesome !

[unknowmOOsewasfound]

Cool video!

[TheTastyCookieez]

I Think That Once Someone Discovers a way to build them faster, and without needing all this sensitive (and expensive) equipment, this will definitely revolutionize computing, gaming, and possibly, even peoples lives (using in hospitals, labs etc.)

Thanks For Sharing!

[jimmyboy3664]

can it run crysis?

[shakemyass9878]

There is so much potential here for AI in games. This would also allow for realtime full scale radiant energy simulation. Seems really cool!

[SkanMLL]

sounds like it makes bruteforce hacking very efficient.

[benwills57]

This might be a dumb question but aren't quantum computers inherently limited by the fact that we need conventional computer technology to interpret them?

[Ploj102]

2 people are amish

[Amaroqdricaldari]

How about a Quantum Spintronic Chemical Computer?

Now that would be pretty powerful.

[Austin25254]

But doesn't collapsing the wave function result in a random quantum state, I don't understand how you could compute with that, can you explain more?

[sakykBzz]

the funniest part is that computers we are using now, looked exactly the same as "quantum computers" look now. i think you catch my drift

[rmhism]

dig the batman shirt.

[andrespereyda]

this guy needs to "overcome the problem" of his terrible accent. you can tell he doesn't know shit by the way he holds that pen. batman? this music? wtf? somebody get him a pb&j sandwich and send him back to kindergarten. he might be better as a skinny gay porn star. wow, shitty video. now let me work on my humility.

[Spartan9092]

Hacking passwords like never before...

[bouchandre]

2030: iMac quantum

[T1Brit]

Very good information video. Nice and fast and a real live quantum computer too. Great stuff.

[EminidisMike]

Don't hackers use quantum computers to invade the Pentagon and government networks to retrieve information?

[redrum41987]

@EminidisMike there is no quantum computer that can accomplish that. i know back in 2008-9 IBM's quantum computer could only calculate 5 x 3=15. but they are still a long ways away from being able to hack anything.

[bouchandre]

@EminidisMike Transformers?

[vinsta76]

Be scared!! A single quantum computer will be able to crack the most highly encrypted file and/or network in a second!!

I forsee lots of serious cyber attacks when terrorists get their hands on one.

[DJKloop]

@vinsta76 d-wave have built the first 128 qubit computer and was sold to lockheed martin for a cool $10 million.

[FelipeDC]

What's the name of the presenter? he is cute

[DrSpock71]

can you play angry birds on it? ;)

[haruhiniwa]

This should be called quantum computing for dummies, i mean... this is nice, it is really well explained.

[imranidz]

Yeah , but does it run Crysis 2 ?

[EvolutionXEngine]

the person who dislike this video was ready to write down the equipment needed to build a quantum computer

[EvolutionXEngine]

can someone tell me from the top of your head... what university has quantum computing?

[TheCoolMovement]

@EvolutionXEngine MIT

[donaldstafford]

Respond to this video...  wish i was born in the quntam computer era

[turgore]

I want a quantum game console.

[johannesboeck]

That's not completely right what you're saying in this video. There's no known quantum algorithm to solve the travelling salesman problem. There are known quantum algorithms for other popular problems like factoring or discrete logarithms, but up until now, it's not expected that quantum computers can solve NP complete problems like travelling salesman.

[xkill3rx]

BBBBBBBBBBBBBBOOOOOOOOOOOOOOOO­ORRRRRRRRRRRRRRRRRIIIIIIIIIING­GGGGGGGGGGGGGGGGGGGGGGGGGGGG!!­!!!!!!!!!!!!

[MrJacify]

Powa

[JunkComa]

it will be at least 40 years before we will see them in shops and even then they will cost the earth...

[bhrzali]

we don't need to have one quantum computer each of us. We can share a super Quantum computer over the cloud

[dominicwalliman]

@bhrzali Yep you are totally right, I think this is exactly how we will use quantum computers in the future. We'll send them our difficult jobs and they'll send back the results.

[andrespereyda]

@dominicwalliman wrong, we'll do everything by thinking, without "technology"

[HelloQro]

@dominicwalliman but that would go against what the hackers at MIT and standfort figth against, i mean, we would be slave to the IBM model again, going backwards can't be the future of compitung.

[milesdavidsmith]

@dominicwalliman That's how classical digital computers began, though. IBM mainframes connected over telephone lines to very rich people's teletype terminals. Nobody EVER imagine that you could have an ultra-powerful supercomputer in your own home, let alone in a square centimeter die! The quantum computer will ignite a revolution.

[sirachman]

@dominicwalliman After that they will be built atom by atom and embedded in everything.

[Designandrew]

@dominicwalliman maybe in the near future, but in a long time scale, you could "RDP" into these machines via the net. Companies like google could have these in their data centers, and they charge for use of the PC over the net.

[andrewyaoauatauabaea]

@bhrzali

I disagree. A quantum computer could easily solve any problem on its own that a cloud of them could.

[bhrzali]

@andrewyaoauatauabaea do some research on cloud computing

[andrewyaoauatauabaea]

@bhrzali

present an argument

[ufoengines]

Is Wikileaks using a Quantum Computer to hack secret data bases to get their info?

In WW2 the Britts used a secret electronic computer to hack codes to German subs. The result, German subs were getting sunk all over the Atlantic.

Has Wikileaks used their secret Quantum Computer to hack the world's state secrets?

[azzam657]

Best explanation I've even seen for the difference between the classical computer and the quantum one

Thanks

[dominicwalliman]

@azzam657 You are very welcome :D

[czubinm]

Love the video! But I do have to note we don't yet know if BQP = NP whereas traveling salesman is NP-hard.
