Takashi Mihara · Institutional Repositories DataBase (IRDB) · 1996
A computation is an evolution from one physical state to another, and so are Today’s computers, i.e., the computations of them are changes of electric signals. What are differences of quantum computers from classical computers? The computational principles of classical computers are based on classical physics. In principle, we can construct them from devices based on classical physics
