For instance, a coherent state describes the oscillating motion of a particle confined in a quadratic potential well (for an early reference, see e.g. Schiff's textbook [3]). The coherent state describes a state in a system for which the ground-state wavepacket is displaced from the origin of the system.
Coherence (physics), an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference Coherence (units of measurement), a derived unit that, for a given system of quantities and for a chosen set of base units, is a product of powers of base units with no other proportionality factor than one
To produce coherent light he passed the monochromatic light from an emission line of a mercury-vapor lamp through a pinhole spatial filter. In February 2011 it was reported that helium atoms, cooled to near absolute zero / Bose–Einstein condensate state, can be made to flow and behave as a coherent beam as occurs in a laser.
Coherent information is an entropy measure used in quantum information theory. It is a property of a quantum state ρ and a quantum channel N {\displaystyle {\mathcal {N}}} ; intuitively, it attempts to describe how much of the quantum information in the state will remain after the state goes through the channel.
