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. WebOct 1, 2024 · The photon cannot impinge on both detectors at the same time, and so photon antibunching is seen as the photon coincidence drops to zero: g 2 Δ t = 0 → 0, limited only by the finite signal-to-noise ratio of the detection. 15 15.
