Is it possible that a macroscopic object tends to a separable state without the need for objective collapse?
For a multi-particle system, superposition is in some sense equivalent to entanglement; with the Dirac field being treated as classical under second quantization, for example, we could at least argue ...

Have objective collapse theories been ruled out by recent experiments?
Have objective collapse theories been ruled out by recent experiments, such as the entanglement of macroscopic objects? (vibrating drumheads)

Wave function collapse for experimental quantum state preparation
Has the John von Neumann projection, or the wave function collapse, been used in the experimental preparation of quantum states? As an illustration, for a pair of EPR-type entangled 2-level atoms
$$|\...

Quantum entanglement information through time of collapse
(I've tried my best to find an existing question that asks this question exactly)
From what I understand, given two entangled particles, one held by Alice and one by Bob, when a measurement is done by ...

Wave function collapse, EPR paradox and information transfer
For a classical formulation of the EPR paradox, two particles are produced, with total momentum zero and separated by a long distance. So say we measure the momentum of one particle first, and measure ...

Has there been experimental evidence that entangled state collapses simultaneously?
If we observe the observable of one particle among two particles which are entangled each other and separated far away, we can determine the value of the other particle’s same observable from the ...

Instantaneous quantum features
Two of the most striking quantum oddities are entanglement and the wave-function collapse or state vector reduction.
Firstly, quantum entanglement is the quantum phenomena involving states of ...

Decoherence/wave function collapse between entangled photon pair
If photon 1 and 2 are position entangled and they go in different directions, would making a measurement on photon 1 effect photon 2? If photon 1 is detected can photon 2 still create interference?
