sub-field of quantum physics and optics

method of population inversion

electronic noise which can be modeled by a Poisson process

quantum mechanical phenomenon

a quantum state that is an element of a Fock space with a well-defined number of particles (or quanta)

important process in quantum optics, used especially as a source of entangled photon pairs, and of single photons

The Wigner distribution function in physics as opposed to in signal processing

quantum state in which an observable has an uncertainty smaller than that of a coherent state, compensated for by a larger uncertainty in the conjugate observable

propagating atomic wave

In physics, superradiance, superradiant scattering or superradiation, is the radiation enhancement effects in several contexts including quantum mechanics, astrophysics and relativity.

interference effect of two photons

quantum computer using trapped ions as qubits

process in which the sequential absorption of two or more photons leads to the emission of light at shorter wavelength than the excitation wavelength

Amplifier that uses quantum mechanical methods

quantum optics model describing a two-level atom interacting with a quantized mode of an optical cavity
