Photon state
WebThis state is a superposition of all the different number states (Fock states) all the way from a single photon state to a state that have an infinite number of photons (however, the … WebApr 2, 2014 · To entangle independent photons of different color, researchers use down-conversion to generate two pairs of polarization-entangled photons, labeled (A, a) and (B, b). The frequencies of each pair differ by either 40 or 80 MHz. Photons a and b enter a beam splitter, resulting in a “hypoentangled” state of polarization and frequency.

WebA single-photon state is a quantum state for which there is one and only one photon per pulse. Such a state has a well-defined intensity and, by the uncertainty principle, random phase. This is not to say that it lacks quantum coherence. In fact, a transform-limited single-photon pulse is a quantum pure state.
