Abstract
A high-luminance quantum correlation photon beam generator in which a laser light source () emits a laser pumped light and a parametric crystal () 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 () splits a signal photon beam () from an idler photon beam (), a mode inverter () rotates one of the signal photon beam, () and the idler photon beam () 180° around its geometric center, a phase adjusting means () adjusts phases of the signal photon beam () and the idler photon beam () based on an optical time delay, and a beam coupling means () overlays the signal photon beam () with the idler photon beam () in a common-line polarized annular shape by the mode inverter () to bring them into a quantum correlated state.
