Researchers at the Institute for Quantum Computing (IQC) in Canada have developed a quantum source intended for inclusion in the Quantum Encryption and Science Satellite (QEYSSat) project. QEYSSat will test a communication method known as quantum key distribution and schedule to launch the quantum source next year. It will carry this small quantum source into space to transmit photons with polarization-encoded between the satellite and ground stations on Earth.

SpeQtral, SafeQuantum, Antaris, and QTD Systems jointly announced yesterday that they will collaborate to establish a satellite Quantum Key Distribution (QKD) receiver node in New York City, aiming to enable quantum-safe communications between Singapore, the United States, and Europe. It is reported that SpeQtral will provide satellite QKD technology and quantum optical ground stations, SafeQuantum will be responsible for deploying the optical ground station in QTD Systems data centers and connecting them to the existing Quantum Secure fiber networks.
