  We propose performing quantum optics experiments in an ground-to-space
scenario using the International Space Station, which is equipped with a glass
viewing window and a photographer's lens mounted on a motorized camera pod. A
dedicated small add-on module with single-photon detection, time-tagging and
classical communication capabilities would enable us to perform the first-ever
quantum optics experiments in space. We present preliminary design concepts for
the ground and flight segments and study the feasibility of the intended
mission scenario.
