Scheidl, Wille and Ursin [1] have proposed using the International Space Station<\/a> to test the limits of spooky action at a distance<\/em>. These experiments could help develop global quantum communication systems.<\/p>\n

Part of their plans include a Bell test experiment<\/a> which probes the theoretical contradiction between quantum mechanics and classical physics. A pair of entangled photons would be generated on the Earth. One of these would then be sent to a detector aboard the International Space Station, while the other photon would be measured locally on the ground for comparison.<\/p>\n

According to quantum physics, entanglement is independent of distance. Our proposed Bell-type experiment will show that particles are entangled, over large distances — around 500 km — for the very first time in an experiment…<\/p><\/blockquote>\n

Professor Ursin<\/em><\/p>\n

It is also not really known if gravity plays any role in quantum entanglement. These experiments would be the first to really probe the potential effects of gravity.<\/p>\n
