Antonia Ferrín Quantum Optical Ground Station

The Antonia Ferrín Quantum Optical Ground Station is a next-generation facility for quantum communications with satellites. Its main instrument is an 80cm Ritchey–Chrétien telescope with four ports. One of the ports is equipped with an adaptive optics system. The station further includes quantum receivers, superconducting nanowire single-photon detectors, a classical optical communications system, and configurable beacon lasers supporting a wide range of quantum communication missions.
