Quantum-entangled light from a vibrating membrane

Researchers from the Quantum Optomechanics group at the Niels Bohr Institute, University of Copenhagen, recently entangled two laser beams through bouncing them off the same mechanical resonator, a tensioned membrane. This provides a novel way of entangling disparate electromagnetic fields, from microwave radiation to optical beams

Entanglement, a powerful form of correlation among quantum systems, is an important resource for quantum computing. (...) In particular, creating entanglement between optical and microwave fields would be a key step towards solving the long-standing challenge of sharing entanglement between two distant quantum computers operating in the microwave regime. The result (by researchers at University of Copenhagen) is now published in Nature Communications. Saiba mais...
