Abstract
Disclosed are a quantum-entangled photon-pair light source using a chip-scale atomic ensemble and implementation method thereof. The quantum-entangled photon-pair light source may include an atomic vapor cell configured to generate cesium (Cs) vapor to fill a photon-pair chamber and a processor configured to cause a coupling laser and a pump laser to travel based on the photon-pair chamber and generate a photon pair of a signal and an idler from the atomic vapor cell.
