The world's first quantum satellite, Quantum Experiments at Space Scale (QUESS), launched by China in 2016, has realized the distribution of entangled photon pairs over 1,200 kilometers. It has proved that quantum entanglement, described by Albert Einstein as a "spooky action," still exists at such a distance. As the satellite's lead scientist, Pan Jianwei has a greater goal: to test quantum entanglement between Earth and the Moon at a distance over 300,000 km, which may help research on gravity and the structure of spacetime.
