One of the most important paradoxes in physics is Schrödinger's Cat. At the microscopic level, light and particles behave according to quantum mechanics. This allows them to be in two places at once ...

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 ...

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 ...

Physicists at CERN — home of the Large Hadron Collider — have for the first time made a qubit from antimatter, holding an antiproton in a state of quantum superposition for almost a minute. This ...
