Spin-dynamics of telecom-band optically addressable single Er3+ ions in CaWO4 at millikelivin temepratures
Single Er 3+ ions in CaWO 4 coupled to nanophotonic cavities enable indistinguishable single-photon emission and spin-photon entanglement in the telecom band, forming building blocks for quantum repeater networks. However, spin decoherence from paramagnetic impurities limits fidelity. We investigate spin dynamics of near-surface Er ions (~10-15 nm from surface) as a step toward quantum repeaters and memory.
