Researchers have successfully demonstrated a polarization entangled photon generation rate exceeding 1GHz at 1560nm, meeting a specific European Space Agency requirement for space-based quantum technologies. This breakthrough utilizes engineered periodically poled lithium niobate waveguides that integrate internal pump sources, optimizing compatibility with standard fiber optic infrastructure for secure communication and quantum computing applications.
European Space Agency target met, a gigahertz of entangled photons

The ability to generate high rates of entangled photon pairs is a critical requirement for quantum key distribution (QKD) and quantum information processing (QIP) systems, with QKD offering prospects for a secure society and QIP opening the route to quantum computing. A generation rate exceeding 1GHz of polarization entangled photons at 1560nm, as defined by the European Space Agency, has been demonstrated.
European researchers have met a key requirement for space-based quantum technologies by demonstrating a polarization entangled photon generation rate exceeding one gigahertz. The team reports achieving 1.48GHz, a quantifiable milestone for applications like secure communication and advanced computing, using a novel optical bench demonstrator.…
