Abstract
A reconfigurable QKD transceiver capable of transmitting and/or receiving qubits using a single optical hardware platform. This reconfigurable QKD transceiver enables various link scenarios specially for LEO-ground network, where the satellites have limited engagement time with a ground station. The reconfigurable QKD transceiver may reduce the optics SWaP by 50 percent and may allow for new mission scenarios that were otherwise not feasible with a transmitter only architecture or receiver only architecture.
