Interfacing broadband photonic qubits to on-chip cavity-protected rare-earth ensembles
Abstract
Solid-state emitters enable broadband quantum information storage, but they are affected by decoherence resulting from inhomogeneous broadening. Here the authors suppress this effect via cavity protection at the single photon level in an ensemble of rare-earth ions coupled to a nanophotonic resonator.
