1. skeptic,
   D-WAVE's method is fundamentally different from other methods for implementing a quantum computer, and is more reminiscent of analog than digital computers. Therefore, the meaning of a qubit in their computer is also different from the meaning of a qubit in a more "digital" computer - therefore there is also a meaning to the calibration and adjustment of the qubits so that they are identical in their properties, to symbolize the functions they are trying to find their minimum.
   In addition, they claimed that their computer was 35,000 times faster than a normal computer. Nice, but still not really amazing. That's the difference between a hundredth of a second and six minutes for a standard Intel server processor. What they didn't specify was how much their result improved the result of the algorithm they used on the regular computer.

2. Interesting that IBM is finding a quantum computer of 50 qubits compared to D-WAVE which is already about 500 qubits
   And in the D-WAVE laboratories they are already working on a 1000 qubit processor
   As far as I understand there are currently about 4 methods for implementing a quantum computer that D-WAVE chose one of the newer methods
   which according to them is the "easiest" to quickly implement a quantum computer
   and IBM choose a different method,
   It also adds another layer to the discussion of whether what D-WAVE has done is a quantum computer
   Probably IBM's method was older and more common in research institutes and researchers invested
   Lots of people change their lives with this method
   And suddenly "out of nowhere" a company announces that it is already implementing a quantum computer in a different method, obviously it will not be happy to hear this from someone who receives grants for research in a certain field, according to D-WAVE the situation will be the opposite, more money will also go into the alternative methods, in addition to that, according to them, the catalogers did not read the Their studies and they have a lot of published studies more than any startup company in the world so they claim
   It was always some kind of quote from something they knew because at first D-WAVE took these claims seriously, they thought at the initial stage that maybe they had some kind of problem that they didn't foresee and there is a serious researcher here who sheds light on the problem, but always upon examination it was found that there was no substance to the claim, it was not substantiated On these sciences it belongs more to the psychological sociological field (sounds like a little salt on the wounds),
   According to D-WAVE what they have is a 100% quantum computer and if we also rely on NASA GOOGLE's tests
   And some other universities and research institutes that support their claim that what they probably have is a quantum computer,
   It will be interesting to see which method will be the leader in the field because in addition to the hardware there is also a whole system of software and more that should sit around and give access and convenience in handling these computers,
   In D-WAVE, for example, you have to calibrate each qubit in the initial stage because this is a quantum system that is very sensitive to environmental conditions and differences even in the system itself, and according to them it is not possible to achieve absolute identity in the manufacturing of the components that create each qubit individually at the level that is needed
   So that during activation in the first stage a calibration and comparison is made between the various qubits so that there is an identity between them and they can work together as a quantum system in addition to the example the system needs to be isolated even from the Earth's magnetic field
   Because any environmental noise can destroy the quantum state so that, for example, if there is a quantum computer in Israel, then its masking adjustment will be different than elsewhere because the angle of the magnetic effect is different here than elsewhere,
   It seems that the elite of these computers delayed the understanding of where the quantum world course and the classical beginner would improve
   It goes from an explanation of few scientists to a clearer explanation of engineers
   In their explanation, as far as I understand, the quantum state does not disappear, of course it always exists, it is transferred into another system that interacts with the quantum system that we wanted to preserve and in order to preserve it in the place we want, for example in a qubit, it must be isolated if we want to take advantage of the quantum properties for a form of calculation that is not They can be done on the classic computer

3. Here is a link to a rather impressive lecture by the founder and manager of the D-Wave company
   In which he explains in great depth what they achieved, the advantages and disadvantages, where it stands in relation to the classical processors, he also explains how it answers the different quantum dynamics, and from there you can also understand why there is
   The reason is that in one of the dynamics that is the entanglement, it is not possible to actually check the depth of entanglement of their qubits (meaning whether all 500 qubits work together) and the reason that actually to check (as far as I understand) you need to check something like 2 to the power of 500 states which is impossible, according to him and also the competitors will reach the same conclusion and according to him the solution will be in a simple test of calculating problems that can only be solved in a reasonable time by a quantum computer, this is a bit reminiscent of the problem of self-learning systems
   that you lose the ability in a complex system to understand what is happening inside, which layer was created, which algorithm the system built, and then from a deterministic system (almost under our complete control) we get a system that is less predictable for us,
   One thing I liked about the article is the feeling that he talks about the system like a mechanic talks about a car (albeit in complex terms) but
   Not like something that's in the realms of science fiction for another 100 years, this is something they know very deeply
   With a clear direction where it is going, all the companies and organizations that work with these "heavy guns" too, if it was some kind of misrepresentation they would have raised a black flag a long time ago,

4. This is a link to an interesting article about the attempt to develop living computers:

5. Thank you for referring to Asaf,
   The truth is that there are opinions about what they did achieve and what they did not, some of which I have already read before, some of the issues are older
   But even on what exists today there are opinions, although the various companies and organizations that are among the best that exist today that have examined it do describe it as a quantum computer, the question arises according to what you have raised to what extent it utilizes all of the quantum potential or only part of it is quite difficult to find The correct answer on this is between the opponents and the supporters
   What I have read is people who complain about the difficulty of programming it and that it is not a general purpose computer, it has to be tailored for each performance, but its developers also describe it as the first airplane of the Wright brothers, even a horse at the time could run faster than him, but even then the airplane was not a horse, it was Utilizes another resource that doesn't exist for the horse, he performs something else even if there is a similarity of moving from place to place The rate of development of the quantum computer is quite amazing again according to what is written how deep it is in the quantum field I don't have an answer now, if I have time I will dig a little more around the internet because it's interesting
   In addition to Haniel Koren's question, not that I am far from an expert (I am in the fields of classical computing), but from what I have read and heard in various interviews of scientists from the field, and there is a very large amount today, the quantum computer will not be better in any field than the classical computer, only in certain types of calculations where the classical computer will have to enter and check There are countless states in a linear form, for example we will take an abstract state
   in which there is a huge amount of ways and in each way there are lots of different parameters
   And we will be asked what is the best way, the classic computer will have to enter each way to examine and exit and then move to the next way only when it finishes the last way we will receive the resident,
   Compared to the quantum computer that will enter all the ways at the same time and return with the correct answer,
   But on the other hand if the question is whether this way is good and there is only one way then the quantum computer has no advantage
   on the classic computer,
   So the more ways and modes there are, the more powerful the quantum computer will be, and this also includes how many qubits it has and the connectivity between them, and because of this enormous power, despite the great difficulties in creating a quantum system for calculation, so many people are working on it around the world, there is a feeling that it is on the verge of a revolution Again according to the publications of those who tested it
   And as in the article that another company like IBM is entering the field and plans to release a commercial quantum computer in the coming years
   Their configuration may be different from D-WAVE, looks like in the early days of classical computing

6. Question for experts:
   Will quantum computing completely replace normal computing, i.e. if they succeed in developing very powerful quantum computers (and of course also cheap) then this will lead to the extinction of binary computers completely or are there uses in which binary computing is fundamentally more efficient than binary computing - and therefore will not be replaced?

7. How much does quantum sharpening affect hitcoin and its value? Will this be the beginning of the end for Bitcoin…

8. A D-wave skeptic is not really a real quantum computer but half way but that doesn't stop them advertising it as such.

9. right. I checked on WIRED, where they write that Bam wants to increase it to 50 qubit.

10. And it seems to me that there is a mistake in the article, in the title they talk about 50 quantum bits, and in the article they only talk about 5, this is a huge difference in the calculation power.

11. It's really not clear from the article why exactly they came and how to use this computer. As a start I would ask him to show me the initial number 50 million and compare his result to the number 50 million we already know. If it works then ask him for the next prime number that we don't know yet.

12. What is written in Wikipedia about the quantum computer is no clearer than this article.
    OK - I learned about quantum theory, quantum collapse, Schrödinger's cat, etc., etc., etc.
    But what is not clear is how it works electronically?
    After all, every computer is built from electronic units of a "transistor" electronic switch that can give either zero or one, it is not clear to me how they bring this component to the state, "quanti" will answer - it will wait in the box together with Schrödinger's cat until the whole system decides in which direction it collapses ... and after this domino-like collapse, how does the component "know" that it has collapsed and where?

13. Only a few years ago, some of the best scientists did not believe that in our lifetime, if at all, it would be possible to overcome the very difficult problems of a quantum computer, such as the ability to preserve the quantum state from environmental noises,
    So when the D-wave company a few years ago claimed to have a quantum computer there was a lot of skepticism about it
    Researchers from universities such as USC and various companies such as Google and organizations such as NASA and more... have purchased such computers
    and have tested this computer in recent years and the conclusion of their researchers is that it does implement quantum computing,
    So IBM's message does not exceed the reasonableness, companies have developed simulations of a quantum computer to develop the basic software subject in the programmers even before the arrival of the full quantum computer such as learning the correct syntax although it is clear that it is not possible to perform a calculation with the power of these quantum computers only to specialize in the principles The basis of working with such a computer,
    If the quantum computer is realized and the present signs show that it is then we are facing one of the great revolutions
    In terms of computing power, this is a tremendous breakthrough because there are topics that the classical computer cannot calculate while it has meaning for us and a quantum computer can, when you look at the (cumulative) variety of topics that the quantum computer will touch, it gives the impression that it will have a huge impact on the human race. The civil census 🙂

14. Quantum computer:

    I don't think IBM needs some eager customer to give a royalty to incentivize it to develop a quantum computer. IBM alone knows, and probably better than any of us, what can be done with it.

15. To the previous commenters: the truth lies in the fog. I don't think IBM has a quantum computer. They only allow researchers to use software that seems to work on such a computer. Israbloff (or Yavmelof?). This is actually a common marketing action in the software world - selling a product that doesn't exist yet, and after enough buyers pay up front, the product will be developed (maybe). They try to justify that they want to develop all aspects of the product at the same time. That is to allow users to work on a pretend-product until it really is a product.
    just what? A quantum computer is such a problematic thing that it is difficult to predict when such a computer will actually be operational. There is a Canadian company that claims to have a working quantum computer, but apparently these are just stories. No one can figure out if what they built really works. And when there is a truly working quantum computer, the intelligence agencies will force its concealment for another ten years on the grounds of national security.
    For those who don't understand - have you heard of Wikipedia? There is also in Hebrew...

16. A good idea. I will ask them to write a popular science article.

17. An article that looks like an advertisement to praise and praise IBM, with a lot of bombastic words, and no useful information.
    Or maybe I'm missing some quants in my brain because I was able to tell that IBM is something, but I couldn't understand from this entire article what a quantum computer is, and what is the difference between it and a non-quantum computer?

18. What I want to understand: have they already built a simple version of a quantum computer or have they just revealed to us the plan/direction towards building it? And anyone who has the tools can participate in the research?
