Quantum Computing 'Magic' - Computerphile

Quantum Computing offers a potential sea-change in computer power, but what are the issues with it, why aren't we all using quantum iphones already? Associate Professor Dr Thorsten Altenkirch.

*From Thorsten: "We have updated the hackage package to work with the new monad library. If you want to play with QIO read the paper and download the code and then you can start quantum programming. :-)"

This video was filmed and edited by Sean Riley.

This speaker is fantastic. A wonderful voice for explanation, and always extremely precise in what he says. Everything I hear him say is what Descartes would have called a "clear and distinct idea".

Regardless of the scientific content, is it just me, or does he seem like a super-likeable person??

More quantum computing videos! Love them.

[TechyBen]

"As soon as you look at them." Really... really we should all start at remembering to change that to "as soon as they *interact with something*" as people keep getting "look" muddled up with "person looks" instead of "anything bumps into them". :P

[markturney]

Hands down the best explanation I have yet heard. Thank you for making the extremely complex understandable.

[recklessroges]

Talks intelligently about quantum computing; Writes shor's algorithm in Haskell. I feel that THIS is someone worth listing to about quantum computing.

It’s honestly a miracle that this stuff is just available on YouTube

[shanefera]

I love this area of scientific discovery and exploration. I'm confident we'll both find and not find the answers for which we are looking.

[colemanliam]

one of the best explanations of it ever

[snyke]

Thanks, finally a video about Quantum computing that actually provides information (&links!) about the algorithms, not just the qubits :)

[HyperModzHD]

I'm studying Computer Scienece at Nottingham University next year, Can't wait!

Please make more Quantum Computing videos, its so hard to find good videos from real professors on the topic.

Dr Thorsten Altenkirch? Neat! Can we get some insights into functional programming and Type Theory now? :)

Good video, I really liked his explanation.

I find it interesting, though, that everyone that talks about quantum mechanics tend to choose the interpretation that they like and then tend to talk like that's either the only one or downplay all the others. Most people I've heard talk about the heisenberg interpretation and down play many worlds theory, and this week I heard a completely different "riding-wave" theory. The fact is that there is still too much we don't know, and I think that's presents the biggest reason why simulating a quantum system in a classical system is hard. There might be that "unknown law" that he talks about, and without that "unknown law" I don't see how a classical simulation could be judged as accurate.

This reminds me of the old Far Side comic where some cows are standing around on two legs talking in a field. Then one says "car!" and they are all on all fours eating grass as the car drives by.

Hoped you've had mentioned the IBM project. They offer a kind of quantum language, a visualisation of said language (actually the process can be done both ways), a great tutorial on quantum algorithms and programming, simulated results and for the most important part: They schedule your program upon demand on an available processing slot on their actual 5qubit processor. It's free to study and can easily sign up using your IBM, Google or Github account.

It should be noted (and the video doesn't put enough emphasis on this imo), that quantum computing would be extremely faster than classical computing *ONLY FOR CERTAIN PROBLEMS*. A quantum computer wouldn't be faster for playing video games or browsing the web, it would probably be even slower.

[Morphinwithyou]

Thank you so much for this video. The best explanation is this because he is know this staff! he does not read from a script! It is easy for him and makes it easy for us to understand!

[mikejones-vdfg]

Cool, more on the simulated quantum computer library would be nice!

[Black-Re]

I thought "Is he German?"
Then I looked at his name, which made me happy :)
His accent is really strong though
I still like him :)
(I am German)

More of this topic. Can't get enough.
