WebAug 7, 2015 · Indeed, its phase uncertainty would be maximal, since its photon number uncertainty would be zero. As one example of experimental research into the coherence properties of single photon states, see: "Heralded single Photon Partial Coherence" Phys. Rev. A 82, 023801 (2010). The Fock state (e.g. a single photon) is the most particle-like state; it has a fixed number of particles, and phase is indeterminate. A coherent state distributes its quantum-mechanical uncertainty equally between the canonically conjugate coordinates , position and momentum, and the relative … See more In physics, specifically in quantum mechanics, a coherent state is the specific quantum state of the quantum harmonic oscillator, often described as a state which has dynamics most closely resembling the oscillatory behavior … See more Mathematically, a coherent state $${\displaystyle \alpha \rangle }$$ is defined to be the (unique) eigenstate of the annihilation operator â with corresponding … See more The canonical coherent states described so far have three properties that are mutually equivalent, since each of them completely specifies … 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 generating a … See more 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.
