Photon antibunching
WebAntibunching is a characteristic of light with sub-Poissonian statistics. Observation of antibunching (by means of photon coincidence correlation or second-order correlation) for instance reveals whether there is only a … Webposite effect, or antibunching near 7 =0, and the joint probability density P,(t, t+7') may increase with T from v =0. Such antibunching or negative photoelectric correlation is an explicit feature of a quantum field, ' " and its observation would provide rather direct evidence for the existence of optical photons, unlike positive correlation ...

WebPhoton detections as a function of time for a) antibunching (e.g. light emitted from a single atom), b) random (e.g. a coherent state, laser beam), and c) bunching (chaotic light). τ c is … WebSingle-photon sources have a broad range of applications in quantum communication, quantum computing and quantum metrology. BACKGROUND OF THE INVENTION. A single photon source can be defined as a light source that produces photons that are separated in time. This emission of photons separated in time is also known as photon antibunching.
