There are many quantum mechanics phenomena that people wish to exploit for future computing and communication technologies, but the equipment needed to produce them can be an issue. One of these phenomena is quantum teleportation, and in 2013 researchers were able to realize perfect teleportation using equipment that covered several square meters. Now researchers at the Universities of Bristol, Tokyo, Southampton and NTT Device Technology Laboratories have recreated that perfect teleportation in a device just millimeters in size.

Quantum teleportation could be used to transfer the quantum information in qubits across distances, and is thus necessary for connecting quantum computers on a network, or for building a communication network secured by quantum mechanics. In either case, multiple tables full of optical equipment is too much. By using state-of-the-art nano-fabrication techniques, the researchers were able to build a complete teleportation system onto a silicon chip, which has never been achieved before.

The importance of this research is obvious as it represents a significant step toward practical quantum technologies.
