Back to Analog Computing


Trying to understand how D- Wave quantum computers work, realized that they are not digital computers but analogical machines. It is like כלים שלובים  a machine of multiple communicating vessels where the system settles in a stable configuration which is the solution. Annealing, they say, heating the metal up and then let it cool down slowly, eliminating internal stresses. The solution is reached faster than calculating (digital computation). Imagine a river flowing down from a mountain. It is almost impossible to calculate its course, but the river selects it without effort, instantly. It seems to me simple, and more primitive than a digital computer, but that is because I do not understand anything of what I am writing, may be.
