Quantum teleportation done between distant large objects

The macroscopic quantum spin state of caesium atoms held in a vessel has been teleported to a second vessel 50 cm away – according physicists in Denmark, Spain and the UK, who have performed the feat. Although this distance is far smaller than the 143 km record for the quantum teleportation of relatively simple states, the experiment achieves a different type of teleportation that had previously been achieved only across microscopic distances. The technique can teleport complex quantum states and could therefore have a range of technological applications – including quantum computing, long-distance quantum communication and remote sensing.
