Quantum Teleportation

Researchers have achieved quantum teleportation between ytterbium ions. The ions were entangled, meaning that information could be passed instantaneously between them and without traversing space - it is teleported. The transfer of information between ions (as opposed to photons) represents in important step in establishing quantum memory systems and quantum computing. Quantum computers could allow unbeatable encryption and incredible efficiencies for some computing tasks.
