A New Source for Quantum Light A new device consisting of a semiconductor ring produces pairs of entangled photons that could be used in a photonic quantum processor.

#QuantumLightSources produce entangled pairs of photons that can be used in quantum computing and cryptography. A new #GalliumNitride source opens up the potential to construct a complex #QuantumCircuit, such as a #PhotonicQuantumProcessor, on a single chip. physics.aps.org/articles/v17...
