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.’

    Having watched a significant portion of this video and skimmed the rest; I do not recommend it. It’s mostly rambling.

    Who needs a long introduction by a government clerk?

  3. Sreeprakash Neelakantan on October 19, 2019 at 3:50 pm

    One of the best talks, thanks for sharing this

  4. yobro manson on October 19, 2019 at 3:51 pm

    If its a girl it’s just some "small talk gossip around the kitchen", but I find it extremely sexist that when it’s a man, it becomes some important "talk on breakthrough science". So men can’t have a carefree, frolicking ’round of rumors round the coolers’ . Hmmmppfftt!

    The whole universe is a QC function, self-simulating, self-organizing, algorithm unknown, self-error correcting, ensuring coherence, tackling complexity, ensuring determinism, fine tuning the parameter space, creating life with perfection and with probability one.
    Life is also a QC function, enabling us to repair/regenerate 50-70 billion cells damaged daily at 99.99 % efficiency and at lightning speed, besides producing protein, hormones, enzymes etc., ensuring we survive and evolve.

  7. paul snor on October 19, 2019 at 3:54 pm

    23:45 the use of ‘modulus’ is completely senseless in this expression

  8. Ridge Quinn on October 19, 2019 at 3:57 pm

    I appreciate the speakers time here, and I’m sure they’re extremely knowledgeable.. however I think they were having difficulty dumbing it down for the rest of us. I am pretty interested in quantum mechanics so I could follow along somewhat, but it was difficult even for me to gather what they were trying to portray at certain points. That being said you don’t have to be a brilliant speaker to be a brilliant person and I’m glad they’re at least trying to help the rest of us catch up to all their hard work and dedication.

  9. Kevin McMahon on October 19, 2019 at 3:57 pm

    I have had arguments with people that Quantum Computing will only ever give you a range of probabilities, and never a definitive yes or no answer.
    Quantum Computing is a probable mathematical system and nothing more. You will only get a list of things, and never a single answer. Mathematics is the basis of Quantum science.

  10. Venkat Babu on October 19, 2019 at 3:58 pm

    When parallel lines meet by small disturbance they create warp drive.

  11. UE Peláez on October 19, 2019 at 3:59 pm

    I liked a lot the info in the slides. 👍

  12. Crazozourus on October 19, 2019 at 4:01 pm

    Perhaps our Universe is just a side effect of a quantum computer created by another beings.

  13. Simon Sozzi on October 19, 2019 at 4:02 pm

    1:00 You never get the computer so you call them and tell them and they say "well you did and you didn’t. That’s what you paid for buddy."

  14. Profyt on October 19, 2019 at 4:03 pm

    How can the guy giving a lecture on quantum computing not know how to use the projector???!!

  15. TheBinary0101 on October 19, 2019 at 4:03 pm

    I love the fact that it’s NOT sponsored by Squarespace; or @t; or Audible; or World of Tanks, etc.

  16. Joseph Valle on October 19, 2019 at 4:07 pm

    Very interesting. Intuitive analytics are in existence. If you do not understand this try surfing the web and wonder why the information that you were seeking suddenly popped up.

  17. Hrobjartur Thorsteinsson on October 19, 2019 at 4:07 pm

    10:30 are you kidding me? Practically all computer scientists should know the Netherlands have spawned some of the greatest IT and software engineering innovators of all times! The Netherlands is also the 4th largest IT service exporter in the world – try adjusting that for population 🙂 Philip Ball maybe more informed about the physics, not computer technology.

  18. Max Aggropop on October 19, 2019 at 4:09 pm

    but can it run crysis?

  19. Diego Gigena on October 19, 2019 at 4:09 pm

    Quantum bits or ‘qubits’ can exist in a superposition state of both zero and one simultaneously. This means that a set of two qubits can be in a superposition of four states, which therefore require four numbers to uniquely identify the state. So the amount of information stored in N qubits is two to the power of N E R D S

  20. keefebaby on October 19, 2019 at 4:09 pm

    It’s very interesting the way they keep trying to compare the old fashioned classical computers with the new quantum computers, there is a very big difference you didn’t actually need those computers to run the software you could do it all with pencil and paper if you wanted to, be very slow but can be done,but the problem with quantum computers is they don’t know how to program them even if they could afford a pencil and paper

  21. Dadson worldwide on October 19, 2019 at 4:13 pm

    Just think we plan to put our fate in the control of something answering our most difficult questions but we dont know what ,when ,where or who is coming up with the response or what demension it is in.
    we could literally decide to start ww3 based on asking satan if we shoukd some day .lol just a thought.

  22. Thomas Geist on October 19, 2019 at 4:13 pm

    I’m a fairly clever guy. Very high IQ and a communications engineer. Also taken a lot of computer science classes and at one time could program in 3 languages. The double slit experiment has always fascinated me and I’m sufficiently knowledgable to know something about epistemology and logic. Okay… Listening to this I felt like the child that noticed the King had no close on. Children should not have been allowed in the audience for fear of nightmares.  

    What a complete waste of my time. "Incoherence theory?" Sounds like the entire thing is incoherent. When they can tell me whether to put my chips on black or red and win more than 50% of the time I’ll be impressed; and the boys at Las Vegas will put out hits on these guys so we’ll be back where we started.

    When computers start creating jobs for humans it will be something worth humankind for now the only thing they seem to be good at is taking away the lively-hood of people spying on everyone and stealing their personal data and selling it to governments and corporations .

  24. David Wilkie on October 19, 2019 at 4:14 pm

    Phys-Chem and Geometry in Spacetime is QM-TIMESPACE Principle In-form-ation, instantaneous-infinitesimal Computational processing in Nature. Spectrum Analyzers, Electrophoresis, Fractionation Columns, Sieves, and Mass Spectrometry etc, are Quantum Mechanical factorization devices, in Principle, but refining them to do accurate numerical values is a return to the crystal resonance/pulse fields generation of typical Integrated Circuits, so effective devices will always be of composite components.

    Quanta, another infinite identity of infinite proportions of infinity, the Singularity positioning here-now forever.

    By default reasoning, Quantum Computing is synchronous parallel computation, or superimposed time-slip comparators of data streams as in the example of Gravity Wave-package detection.

    It seems like the Royal i cannot untangle its own audio problems.

  26. garymun420 on October 19, 2019 at 4:18 pm

    I would totally hit that I would seriously though 😂🙈 I’m not joking I want to hit that 😅 she’s hot 😈🔥🔥🔥🔥

  27. paul snor on October 19, 2019 at 4:19 pm

    14:11 and I have heard nothing yet…..

  28. paul klein on October 19, 2019 at 4:21 pm

    Just because it won’t be in your phone in the future unless huge changes happen. The P vs NP problems a Quantum computer could solve would itself propel us even farther into the future.

  30. Theo Schijf on October 19, 2019 at 4:24 pm

    Great story. I would say: the world needs no more than 5 quantum computers. And we will never be able to build them. Great research topic, though. BTW: the factors of 15 are: 3 and 5.

  31. Mel Clifford on October 19, 2019 at 4:24 pm

    And do we take it from this argument that we can’t normalize a wave function over all space and get unity, given that its a quantum wave function?

  32. rayc056 on October 19, 2019 at 4:26 pm

    Babble, babble, random statement, basically. This untangled nothing for me, best of luck to the other viewers.

  33. entermatrix on October 19, 2019 at 4:26 pm

    Will q computer kill bitcoin?

  34. Willi Hansen on October 19, 2019 at 4:26 pm

    I think I’m more confused now than I was before.

  35. Mel Clifford on October 19, 2019 at 4:29 pm

    Oh yes, and were the slides ordered in some non-deterministic way which made it impossible for the lecturer to know which slide came next?

  36. Elery David champion Manifest vanquished Devil on October 19, 2019 at 4:30 pm

    Quickly it hasn’t happened yet I’m from hundred thousand years ahead and haven’t had a soul since passing over at fifteen in nineteen ninety two car accident, becoming one of the first avatar of heaven and every ascension is locked in space time with hidden location in space time continuum collapse prevention of omniverse parallel worlds which creates earth deep in many repeated cycle of ascension and only when I have completed each ascension seven times for each realm regaining consciousness awareness enlightenment tantric yoga elder lore Kraft spirit guide awakening White lighter levels of seven realms ascension levels will I be born mortal for final ascension again with a soul that can be used to devil incantation trap me which by then I’ll be an ascended Masters again preordained past master and risen again timelord time wardon to free every trapped time loop and let earth become the omniverse that over expansion locks time in parelel dimensional anomalies parallel realms giving rise to the souls that saves us and becomes us and then start again later at pre-recorded history of three creations seven ascension five extinction

  37. Ozair Kazi on October 19, 2019 at 4:30 pm

    and it would still take 5 centuries

  38. Goldpenny1 on October 19, 2019 at 4:32 pm

    Should he or should he not know how to use the projector? See! In quantum computing, it really doesn’t matter.

  39. Allan Watson on October 19, 2019 at 4:36 pm

    So, what is the answer to the question? "Yes and no", which is what you expect from a politician. It sounds like "One plus one equals two, but only sometimes!"

  40. Mel Clifford on October 19, 2019 at 4:36 pm

    Is a sum of histories actually a probability sum?

    Until 1:08:58 zzzzzzzzzzzzzzzzz… and then FINALLY it gets a little bit exciting ._.

  44. KK on October 19, 2019 at 4:40 pm

    I’m a classic computer programmer, can you show me some API for Quantum computing? Can’t really understand any bit of maths / physics here and how we’re going to use them for programming.

  45. S. C. Mack on October 19, 2019 at 4:40 pm

    A computer that can and will do whatever the hell it wants. There is your killer AI right there.

  46. Bryan Cooper on October 19, 2019 at 4:41 pm

    My reason for watching this is due to Sean Worthington, inventor of @t – he invented the second technology fixing the "physical Integrity issue" with digital currencies. Quantum Computers are the biggest threat to Cryptocurrencies because the Blockchain is based on cryptography and one of the biggest functions of a Quantum Computer is cracking cryptographic codes. Theoretically a fully developed Q. C. can hack any blockchain based currency in under two minutes. The only "digital" not cryptocurrency is Cloudcoin and is NOT cryptographic and is 100% Q.C. SAFE. This is the anti-blockchain technology – called RAIDA. @t

  47. paul snor on October 19, 2019 at 4:44 pm

    This guy is sloooow..

  48. Kelston Shipley on October 19, 2019 at 4:45 pm

    Bro😐 that was too much to take in

  49. northy Land on October 19, 2019 at 4:45 pm

    Gravitational waves have been detected… When a particle is shot though double split its hitting micro gravitational waves (ripples) and bouncing all over the place, like a ship going around cape horn. When you turn on a measuring device… your adding "momentary mass" to the particle, like adding ballast to a ship so it rides lower and smoother in the ocean (space).

  50. RAUL FERNANDEZ on October 19, 2019 at 4:47 pm

    7:01 why are those women cleaning the device?
