In quantum optics the coherent state refers to a state of the quantized electromagnetic field, etc. that describes a maximal kind of coherence and a classical kind of behavior. Erwin Schr… See more

Mathematically, a coherent state | α ⟩ {\displaystyle |\alpha \rangle } is defined to be … See more

To find the wavefunction of the coherent state, the minimal uncertainty Schrödinger wave packet, it is easiest to start with the Heisenberg picture of the quantum harmonic o… See more

The canonical coherent states described so far have three properties that are mutually equivalent, since each of them completely specifies the state | α ⟩ {\displaystyle |\alpha \rangle } , n… See more

A single mode thermal coherent state is produced by displacing a thermal mixed state in phase space, in direct analogy to the displacement of the vacuum state in view of gen… See more
