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

In quantum mechanics, wave function collapse (also called collapse of the state vector or reduction of the wave packet) is the phenomenon in which a wave function—initially in a superposition of ...

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 ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
