Quantum state diffusion framework makes it possible to characterize quantum measurement in terms of entropy production ...

Quantum mechanics, the theory that governs the subatomic world, rests on a persistent paradox. It describes particles that ...

波動関数とは「物体の状態そのもの」が波動で表されるという関数であり、時にはゲーム内の物理シミュレーションなどに利用されることもあります。そんな波動関数がある1つの固有の状態に収縮することを波動関数の崩壊と呼び、そんな波動関数の崩壊を ...

Quantum collapse models represent a class of theoretical modifications to standard quantum mechanics that seek to resolve the long‐standing measurement problem. They posit that the linear evolution of ...

Einstein agreed. Physicists have proposed many solutions to this puzzle, including that there is never a collapse and, instead, a new Universe is spawned every time a particle is in two places at once ...
