Going the distance may get a boost from a novel repeater architecture
The movement of electrons and photons underlies the transfer of information in conventional electrical and optical communication systems. Information is literally carried over long distances by the movement of these tiny particles in overground, underground and even subsea electrical and fibre-optic cables. Quantum communication takes advantage of quantum entanglement and teleportation, transferring matter or energy from one point to another without physically traversing the distance. Like conventional amplifiers at intermediate ‘nodes’ to reach long distances, quantum communication relies on quantum repeaters. Two concepts have emerged to realise quantum repeaters; however, they have not yet been investigated as a hybrid system combining the strengths of each. The EU-funded project QUREP has set out to do just that via combined theoretical and experimental studies, investigating for the first time an interconnected system of two disparate solid-state resources for quantum communication.
