Coherent state overcomplete
The coherent state describes a state in a system for which the ground-state wavepacket is displaced from the origin of the system. This state can be related to classical solutions by a particle oscillating with an amplitude equivalent to the displacement. 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 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 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 coherent state.

WebThe phrase coherent states refers to a set of vectors in Hilbert space that enjoy several properties. The most widely accepted definition involves a continuous parametrization and a resolution of unity that involves a weighted integral over one dimensional projection operators onto the set of coherent states. Generic Formulation
WebShow that the time evolution of the coherent state j iis given by e iHtj i= je i t i: i.e., the state remains coherent. Through exact analogy between the noninteracting bosons occu-pying the same energy level and the single-particle harmonic oscillator problem, one can introduce coherent harmonic oscillator states and solve for their evolution. 2 WebOur implementation of FFCC runs at ~700 frames per second on a mobile device, allowing it to be used as an accurate, real-time, temporally-coherent automatic white balance algorithm.
