Optically-interfaced spins in the solid state are a promising platform for quantum
technologies. A crucial component of these systems is high-fidelity, projective measurement …

Rare-earth ions in crystals are a proven solid-state platform for quantum technologies in the
ensemble regime and attractive for new opportunities at the single-ion level. Among the …

We present a quantum repeater scheme that is based on individual erbium and europium
ions. Erbium ions are attractive because they emit photons at telecommunication …

We design a quantum repeater architecture using individual 167 Er ions doped into Y 2 SiO
5 crystal. This ion is a promising candidate for a repeater protocol because of its long …

The Duan-Lukin-Cirac-Zoller (DLCZ) scheme is a potential method to establish remote
entanglements and realize large-scale quantum networks. Here we propose a DLCZ-like …

We characterize the europium (Eu 3+) hyperfine interaction of the excited state (D 0 5) and
determine its effective spin Hamiltonian parameters for the Zeeman and quadrupole tensors …

Rare-earth ion doped crystals have proven to be solid platforms for implementing quantum
memories. Their potential use for integrated photonics with large multiplexing capability and …

Stoichiometric rare-earth materials have demonstrated extremely narrow inhomogeneous
photoluminescence-excitation linewidths because the rare-earth cations occupy uniform …

The medical imaging technique called “ultrasound optical tomography”(UOT) entails light
scattered in tissue that is given spatial information by interacting with an ultrasound field …

Single atoms and atom-like defects in solids are promising platforms for realizing single
photon sources and long-lived quantum memories, which are essential ingredients for the …
