Quantum technology has the potential to revolutionise whole fields of computing; from cryptography to molecular modelling. But how do quantum computers work?

Join leading experts to untangle the quantum computing hype, at this event supported by the Embassy of the Kingdom of the Netherlands.
Artur Ekert works on information processing in quantum-mechanical systems. His invention of entanglement-based quantum cryptography in 1991 triggered an explosion of research efforts worldwide and continues to inspire new research directions. As well as showing that Bell’s inequalities can be used to test for eavesdropping, he has contributed to many important advances in the foundations and experimental realisations of quantum communication and computation. He has played a leading role in transforming quantum information science into a vibrant interdisciplinary field.
Harry Buhrman got his PhD in Computer Science from the University of Amsterdam. Buhrman built the quantum computing group at CWI, which was one of the first groups worldwide and the first in The Netherlands working on quantum information processing. Buhrman’s research focuses on quantum computing, algorithms, and complexity theory. He co-developed the area of quantum communication complexity (quantum distributed computing), and demonstrated for the first time that certain communication tasks can be solved (exponentially) more efficient with quantum resources. This showed that quantum computers can not only speed up computations, but also communication – which opened up a whole new application area of quantum information processing. Buhrman co-developed a general method to establish the limitations of quantum computers, and a framework for the study of quantum algorithms, which is now textbook material.
In 2001, Harry Buhrman became professor of algorithms, complexity theory, and quantum computing at the University of Amsterdam (UvA) and group leader of the Quantum Computing Group at the Center for Mathematics and Informatics (CWI). Buhrman co-founded QuSoft in 2015, a research center for quantum software, for which he is also co-director. During his career, Buhrman obtained various prestigious awards. Buhrman also has a leading role in the national Quantum Software Consortium that was awarded an NWO Gravity grant in 2017.”
The event is chaired by award-winning science writer Philip Ball, whose latest book is entitled ‘Beyond Weird: Why Everything You Thought You Knew About Quantum Physics Is Different.’

Disappointing
The first bald guy is a just a total mess ….
Artur Ekert part of lecture starts at 11:45
Harry Buhrman part starts at 59:50
Arthur, provided some very poor explanations, it was as if he didn't know what he was talking about.
I have no doubt that these people know what they talk about. However, they are pretty horrible at communicating their knowledge. I'm not referring to that they have English as a secondary language, but the fact that they jump between the topics without really explaining why. "Detectors clicked so you see that Q-bits are useful". Then they move on. I have a feeling that they should have blocked out 75% of what they wanted to say and then actually explained the last 25%. Right now it's just random facts, arbitrary statements (that probably makes sense to them..) and forced conclusions that assumes you already are familiar with the subject.
Terrible speakers. I'm sure they are intelligent but they ramble and wander aimlessly. It's boring.
Ladies and gentlemen I appreciate your focus to 26:40, the place where the whole essence of the talk reveals before us. And you are welcome.
The biggest question will be:
Will it run Crisis?
On a serious note why did he not show how to link the photons? 1:11:00
That would have been the most interesting thing here, the other stuff was boring
meaning either to high or low to make sense to a "normal person"
Deadly boring and lifeless,
Quantum computers doing lectures on quantum computers… :o)
I love quantum theory but my head hurts to understand it. Anyone who has the guts to explain it is a good person by my vote.
Quantum Computer: Your electric bill might be $2, or $2 Million. Due to the Uncertainty Principle, we don't know!"
I don't get it
another slow motion video……… 2x speed is not enough
51:18 The Hitchhiker's Guide reference 🙂
"I don't really feel like a prophet to be able…" you are a very modest man, this was the best talk I've heard so far about quantum computing. I hope to hear more of you.
11:45
Reminds me of computer architecture in university ZZzzz…
Great talk, thanks! Lots of examples to get a feel for the field. I liked the engineer and light bulbs example as an analog how to make use of the physical processes rather than just the mathematical abstraction.
The hype is real. Get your degrees, the thought revolution has started. If you take nothing else away from this, realize this is no longer just theoretical science, it’s engineering.
The first speaker is no doubt very well versed but quite incapable of explaining how a quantum computer works.
I agree that the speakers ramble… Just watch at 1.25 or 1.5x speed. Makes it much better
Horrible explanations… It's like listening to someone trying to say everything without saying anything really. 🙁
just rotate the spin of a qbit and use microwave pulses to measure their binary signals already…sheesh ! (im not from here)

Amazing
This talk sounds elitist and lazy. It's not effective or inspiring science explaining. Unlike the other excellent talks in the series.
O my God. how bad comunication skills they have !! PLEASE work on that, your brains are so amazing, you can do much bettter for sure! Big Hug!
The light switches puzzle was cool. And LED lights get warm too. The second speaker obviously never had to install LED lighting nor should he.
I love the fact that it's NOT sponsored by Squarespace; or Brilliant.org; or Audible; or World of Tanks, etc.
I need "Quantum computing for dummies"
zzzzz …. Yes, these speakers definitely killed ANY hype there might have been before watching. Had to force myself through this one.
So boring. Didn't watch. Bad RI!
When you watch science vids to go to sleep but now YouTube thinks you like science vids
typical quantuum rubbish. There wasnt all this fuss about coproccesors or graphics proccessors. just a processor that cant do very much compared to a standard cpu…
How do you do I/O, in view of the principle of indeterminacy?
video starts at 15 mins. before that its just people introducing and reintroducing themselves.
SOLVED: I needed the statement AND/OR during patent composition where I soon discovered that there are cases for OR to be used as a declaration of inclusion and exclusion (English language). I needed to create the operator AND/EITHER which states inclusion/exclusion to remedy the problem of AND/OR being interpreted as inclusive/inclusive.
I need to submit AND/EITHER for inclusion to Wikipedia.
A better logical operator for the age of quantum computing.
Where substitution of the archaic AND/OR operator is necessary, declaring the new operator as AND/ET can preserve file length and line breaks amongst existing compositions, legal documents and computing code. https://steemit.com/hash/@deanpiecka/new-logic-and-technologies-developed-during-the-last-three-years
