ABSTRACT:
A high-luminance quantum correlation photon beam generator in which a laser light source (1) emits a laser pumped light and a parametric crystal (2) generates a pair of two photons of a signal photon and an idler photon on receiving the pumped light to emit two photon beams. Further, a beam splitter (5) splits a signal photon beam (6) from an idler photon beam (7), a mode inverter (10) rotates one of the signal photon beam, (6) and the idler photon beam (7) 180° around its geometric center, a phase adjusting means (8) adjusts phases of the signal photon beam (6) and the idler photon beam (7) based on an optical time delay, and a beam coupling means (14) overlays the signal photon beam (6) with the idler photon beam (7) in a common-line polarized annular shape by the mode inverter (10) to bring them into a quantum correlated state.
