KnowraCoherent stateLinked fromLinked fromThe 8 pages that link to Coherent state, each with the reason it gives.All 8Broader topic 3Related 2Compared with 3Quantum harmonic oscillatorRelated: It contrasts classical-like motion with the oscillator’s number states, which have definite energy.Superposition principleCompared with: It is a specific quantum state, unlike the general additive rule for linear physical responses.Quantum opticsBroader topic: Laser light is often modeled as a coherent state, linking classical waves to photon descriptions.Classical limitRelated: It provides oscillator states with especially direct classical-like dynamics.Roy J. GlauberBroader topic: Coherent states provide the quantum description of ideal laser light in his framework.Ehrenfest theoremBroader topic: Coherent states show how narrow quantum distributions can sustain classical-looking averages.Hong–Ou–Mandel effectCompared with: Coherent-state inputs do not exhibit the same complete coincidence cancellation as one photon in each port.QED vacuumCompared with: A populated coherent electromagnetic field is not the no-real-photon vacuum state.
