Description

Quantum networks are based on the distribution and utilization of entanglement among many nodes. Some of the more interesting applications of these networks depend on the ability to produce entanglement in a form that enables the implementation of teleportation and entanglement swapping protocols. In the absence of quantum memories, this requires the production of entanglement in tight time windows that enables the execution of joint measurements among photons from independent sources. This project aims to develop a high-quality pulsed source that avoids the use of large lasers typically used in teleportation and entanglement swapping demonstrations. The existence of such a source will be important for the establishment of long-distance quantum networks, particularly for eventual satellite applications. SQT will use its existing CubeSat format entanglement source as a starting point for developing this pulsed, low SWaP entanglement source.
