Lissafin quantum

Lissafin quantum yana amfani da superposition da entanglement. Richard Feynman (1982) ya nuna cewa kwamfutoci na yau da kullum ba za su iya kwaikwayon tsarin quantum na yau da kullum yadda ya kamata ba, kuma ya ba da shawarar kwamfutocin quantum a matsayin magani.

Matakin Quantum, entanglement cikakke an lissafa shi ne ga na’urar gargajiya ta yau da kullum, wadda dole ta adana amplitudes 2^(ɓarbashi). Wannan shi ne cikas da Feynman ya bayyana.

Ra’ayin Feynman shi ne cewa kwamfutar gargajiya tana buƙatar lambobi 2^N don kwatanta ɓarbashi N masu entanglement. Matakin Quantum, entanglement cikakke shi ne wannan lamba ga duk sararin samaniya. Shi ne saiti ɗaya da ke tura jimilla ta wuce ma’auni, domin exponent ɗin kansa yana buƙatar exponent.
