The Race to Quantum Technologies and Quantum Computers (Useful Links)

One of my main research directions in the last decade is  quantum information theory and quantum computers. (See this post and this one.) It is therefore a pleasure to report and give many links on the massive efforts carried out these days in these directions and the great enthusiasm and hope these efforts carry.

Updates: I will try to update this post by adding new items at the end (and some important older items that I forgot to include). Update 1, April-May 2017, posted May 24, 2017.

An article with emphasis on difficulties, bringing also  my point of view.

A general article: The trouble with quantum computing by Ben Skuse, Engineering and Technology. The author expresses overall an optimistic bottom line, but explains the difficulties and also brings my point of view.

Here is the ending paragraph:

Much like outcomes in the quantum world itself, the future of quantum computing involves a number of unknowns, none of which we can predict. When and whether quantum supremacy and universal quantum computers can be achieved is currently up in the air, but the work of Chow, Lucas, Montanaro and even Kalai is contributing to tilting the odds in its favour. And each ‘step closer’ is only that. The road to quantum computing stretches off into the distance and may have no end.

Post quantum cryptography

Quantum computers will allow breaking most of current cryptosystems. This leads to much effort for “post-quantum cryptography,” namely developing cryptographic methods immune to quantum attacks.

  2. Dyakonov says:

    Gil, you know what I think about this: irresponsible hype with a quasi-scientific appearance.

    • Gil Kalai says:

      Dear Michel, I expressed my view many times and I decided to be nice this time 🙂 . I prefer the word “hope” on “hype,” and I do think that this is a scientific question that the “race” and immense efforts will shed light on.

  3. mvasx says:

    Portuguese: Computadores quânticos
    🙂

  4. mvasx says:

    Japanese: 量子コンピュータ

    The “量子” part refers to quantum (the first kanji is related to measurements and the second one to a particular state of an object, a diminutive for some cases. So, quantum is the measure of the small things. The “コンピュータ” part is just the katakana writing for “conpiu-ta” (yep, this is “computer”).

    The reading for 量子コンピュータ is りょうしコンピュータ, which is something like: “rioshi conpiuta”. It is not possible for me to put the pronunciation details here, though.

  5. German: Quantencomputer

  6. vznvzn says:

    😀 😮 ❗ lol @ Dyakonov, found your papers years ago & very much enjoy them, & think you have many great points, but, looks like large paradigm shift in play, & sorry, looks like QC skeptics are on the losing side now. see also “gartner hype curve” for more on expectation vs reality.

    https://en.wikipedia.org/wiki/Hype_cycle

    lets note however that Kalai can actually be regarded as in the skeptic column to a large degree wrt noise difficulties. which looks like the last major debate: how much can experimental QM reflect theory wrt noise considerations? seems like comprehensive theory of thermodynamic entropy wrt QM computing may still be yet to be written…

  7. Gil Kalai says:

  10. Matthew Cory says:

    I don’t see how the threshold theorem has anything to do with quantum computers, if you realize, like a competent mathematician or scientist, that the uncertainty principle implies all of quantum mechanics. That means under a standard (or rehashed QBism) view, we must admit that the situation could simply reduce to analog computational limits. It’s an INTERPRETATION of the physics that talks about sub-planck “negative probabilities” in pseudo-CLASSICAL distributions. There is NO PROOF IN SCIENCE for these views. NONE! They are stated dogmatically but underlie the actual differences of opinion. The lack of clear language on this point is quite astounding. A cat is not “smeared” over a distribution but the probability is. It might help to eliminate the regressive primary narcissism that eliminates the distinction between the subjective and objective. Bayes isn’t exactly new.
