WebThe probability that two photons exit the medium simultaneously was suppressed by the blockade mechanism, resulting in photon antibunching g ð2Þ ð0Þ < 1, as seen in Fig. 15(b). 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.
