Margolus–Levitin theorem : ウィキペディア英語版 | Margolus–Levitin theorem The Margolus–Levitin theorem, named for Norman Margolus and Lev B. Levitin, gives a fundamental limit on quantum computation (strictly speaking on all forms on computation). The processing rate cannot be higher than 6 × 1033 operations per second per joule of energy. Or stating the bound for one bit: :A quantum system of energy ''E'' needs at least a time of to go from one state to an orthogonal state, where ''h'' = 6.626 × 10−34 J·s is Planck's constant. The theorem is also of interest outside of quantum computation, e.g. it relates to the holographic principle, digital physics, simulated reality, the mathematical universe hypothesis and pancomputationalism. == See also ==
