Photon number phase uncertainty
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. Erwin Schrödinger derived … 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 oscillator for … See more • A Bose–Einstein condensate (BEC) is a collection of boson atoms that are all in the same quantum state. In a thermodynamic system, the ground state becomes macroscopically occupied below a critical temperature — roughly when the thermal de Broglie … See more WebAug 7, 2015 · Indeed, its phase uncertainty would be maximal, since its photon number uncertainty would be zero.
