Title:
MULTI-PHOTON ENTANGLED LIGHT SOURCE
Document Type and Number:
WIPO Patent Application WO/2021/043201
Kind Code:
A1
Abstract:
The present application provides a multi-photon entangled light source, comprising a laser. A working substance of the laser has a parity. The laser comprises an optical resonant cavity. The optical resonant cavity is a parallel plane standing wave cavity, and comprises a laser output end and a total reflection end opposite to the laser output end. The working substance is subjected to stimulated radiation in the optical resonant cavity to generate a laser in a two-photon entangled state. The laser in the two-photon entangled state propagates back and forth in the optical resonant cavity and is amplified to generate a multi-photon entangled laser. The total reflection end totally reflects the multi-photon entangled laser incident thereon, so that a macro-scale multi-photon entangled laser in a single entangled state is emitted from the laser output end. The multi-photon entangled light source provided by the present application can enable the multi-photon entangled laser output from the laser output end to have a single entangled state, and therefore can be applied in applications such as quantum computing, quantum detection, and quantum communication without performing corresponding processing.
