My intuition tells me the same thing, now that we know for sure that what Einstein called "spooky action at a distance " is real it seems to me there must be some way to put this interesting scientific phenomenon to work to our technological advantage. And quantum computers do that but conventional computers do not. By the way, there is a new result that does not prove a quantum computer could solve all nondeterministic polynomial time problems in polynomial time BUT it does PROVE that even if P=NP and even if we had an algorithm that could solve NP problems on a conventional computer in polynomial time there would STILL be a class of problems that a conventional computer could NOT solve efficiently but a quantum computer COULD. Although I must admit that this is a class of very exotic problems that were recently discovered that may be of fundamental interest in themselves or they may be interesting for no reason other than that a conventional computer can’t solve them but a quantum computer can. This is so recent nobody knows yet.
