Understanding Coherence in Quantum Mechanics

[Sheldon Cooper]

Hi,

Can anyone please explain the physical meaning of coherence(Quantum Mechanics).

Thanks is advance

Physical meaning of coherence would be that beams of particles (or two parts of the same beam) are coherent if they show interference pattern when they overlap with different offsets.

 

[A. Neumaier]

Read https://en.wikipedia.org/wiki/Coherent_state and then ask about what you still don't understand.

 

[Demystifier]

A term "coherent state" has two different meanings: a narrow one meant by A. Neumaier and a broad one meant by zonde.
