Multimode and Long-Lived Quantum Correlations Between Photons and Spins in a Crystal
Multimode and Long-Lived Quantum Correlations Between Photons and Spins in a Crystal
The realization of quantum networks and quantum repeaters remains an outstanding challenge in quantum communication. These rely on the entanglement of remote matter systems, which in turn requires the creation of quantum correlations between a single photon and a matter system. A practical way to establish such correlations is via …
