Quantum Teleportation

Physicists passed a milestone in the development of a 'quantum internet' by transmitting quantum states between telescopes on La Palma and Tenerife – a record distance of 143km. The visible laser beam was used to stabilise the telescopes sending and receiving the quantum signal. In theory, 'quantum teleportation' will enable the exchange of messages with greater security, and allow calculations to be performed much more efficiently than is currently possible source:
