A coherent state is a special type of [[Quantum State|quantum mechanical state]] that reflects some properties of [[Wave|classical waves]]. Coherent states satisfy the [[Heisenberg Uncertainty Principle|Heisenberg uncertainty principle]] with the smallest possible product of uncertainties (for example, position and momentum uncertainty). *Coherent states* are of practical importance, for example, in the description of [[Laser|lasers]]. >[!read]- Further Reading >[!ref]- References
