Quantum Computing Quotes

“As noted previously, there are a number of other algorithms beyond search, prime factors and Monte Carlo methods, though many of these apply only to very specialist mathematical problems and may never have practical applications. As yet, though, the range available is relatively limited. Some of this may be due to the limitations that are imposed in dreaming up algorithms without an actual device to run them on, but it is entirely possible that the list will always be fairly short, as we shouldn’t underestimate the difficulties of getting quantum algorithms that will run. However, Lov Grover commented in an interview with the author a while ago: ‘Not everyone agrees with this, but I believe that there are many more quantum algorithms to be discovered.’
Even if Grover is right, quantum computers are never going to supplant conventional computers as general-purpose machines. They are always likely to be specialist in application. And, as we shall see, it is not easy to get quantum computers to work at all, let alone develop them into robust desktop devices like a familiar PC.”

“is uncertain’ or that ‘anything goes’. In fact, it is a clear mathematical statement. It reflects the way that different aspects of the physical world are intimately connected at the quantum level. Its best-known formulation is that the more accurately you know the position of a quantum particle, the less accurately you know its momentum.†† It is impossible to know both perfectly at the same time.”

“Immensely simplified, quantum physics has two rules: Very small things don’t have locations, we just have probabilities of where they are. The first rule only works if these very small things don’t interact with their environment.”
