Confusion about reversible/quantum computers
It seems that in order to have the a physically reversible process, an therefore a reversible computer, decoherence must be avoided and the stochastic nature of quantum mechanics must be preserved until the algorithm completes, i.e. a quantum computer. Wikipedia, however does not seem to think this and talks about how a physically reversible computer must start with logically reversible binary gates, which seems to me to already be flawed. While logically reversible gates would indeed avoid the loss of that one piece of information (one bit for a 2-input AND gate for instance), that would surely be negligible in comparison to the irreversible information loss associated with a macroscopic measurement necessary for a deterministic binary logic gate. Did I miss something?
Any help will be apprecited.
I didn’t find the right solution from the Internet.
