Abstract

Space offers a very unique environment for quantum physics experiments at regimes for distance and velocity not possible on ground. In the recent years there have been a range of theoretical and experimental studies towards the feasibility of performing quantum physics and quantum information science experiments in space.   The most advanced quantum application is quantum cryptography,  known as quantum key distribution (QKD),  which can be extended to global distances by bringing suitable quantum systems into space.  It is interesting to note that with quantum satellites in Earth's orbit, we will be able to perform tests on the validity of quantum physics and entanglement at huge length scales and velocities. This could provide a possible route towards gaining  insights into the interplay of quantum physics and relativity. I will review some of the interesting quantum entanglement tests that can be performed with satellites in space. I will also outline a proposed satellite mission that is based on existing technology on a small-scale satellite, and could be a first important step into this direction.
