New Bell state analyser for photonic integrated circuits
Applications: Quantum networks, quantum computing, communication networks
Sharing entanglement across networks is a key requirement to for long range quantum computing and networks. Current Bell state analysers require optical polarisations to be conserved, challenging for photonic integrated circuits. The Oxford invention is easily implemented in photonic integrated circuits.
Features
Benefits
Bell state analyser swaps quantum entanglement of photons
Enables long range quantum communication and networks
Unlike previous Bell state analysers, different optical polarisations travel through different paths
Analyser can be produced as photonic integrated circuit, avoiding bulky optics
