Rare-earth (RE) ion doped nano-materials are promising candidates for a range of quantum technology applications. Among RE ions, the so-called Kramers' ions possess spin transition…
Indistinguishable telecom band photons from a single erbium ion in the solid state
Salim Ourari, Łukasz Dusanowski, Sebastian P. Horvath +8
Atomic defects in the solid state are a key component of quantum repeater networks for long-distance quantum communication. Recently, there has been significant interest in rare ea…
Stark control of solid-state quantum memory with spin-wave storage
Mohammed K. Alqedra, Sebastian P. Horvath, Adam Kinos +3
Quantum memories for quantum communication need to be able to store photons for an extended time and then to release them on demand. This can be achieved in atomic frequency comb e…

Erbium-doped materials can serve as spin-photon interfaces with optical transitions in the telecom C-band, making them an exciting class of materials for long-distance quantum comm…
Slow Light Frequency Reference Cavities -- Proof of Concept for Reducing the Frequency Sensitivity Due to Length Fluctuations
Sebastian P. Horvath, Chunyan Shi, David Gustavsson +4
Length changes due to thermo-mechanical noise originating from, for example, Brownian motion are a key limiting factor of present day state-of-the-art laser frequency stabilization…
Experimental implementation of precisely tailored light-matter interaction via inverse engineering
Ying Yan, Chunyan Shi, Adam Kinos +6
Accurate and efficient quantum control in the presence of constraints and decoherence is a requirement and a challenge in quantum information processing. Shortcuts to adiabaticity,…
