Optical coherence properties of Kramers' rare-earth ions at the nanoscale for quantum applications
Mohammed K. Alqedra, Chetan Deshmukh, Shuping Liu +12
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…
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,…
Noise Free On-Demand Atomic Frequency Comb Quantum Memory
Sebastian P. Horvath, Mohammed K. Alqedra, Adam Kinos +4
We present an extension of the atomic frequency comb protocol that utilizes the Stark effect to perform noise-free, on-demand, control. An experimental realization of this protocol…
Optically unstable phase from ion-ion interactions in an erbium doped crystal
Yu-Hui Chen, Sebastian P. Horvath, Jevon J. Longdell +1
We demonstrate an optical unstable phase for a laser driven erbium ion ensemble. The transmitted light through an erbium-doped yttrium orthosillicate crystal becomes dynamically un…
Long spin coherence times in the ground state and an optically excited state of Er:YSiO at zero magnetic field
Jelena V. Rakonjac, Yu-Hui Chen, Sebastian P. Horvath +1
Spins in solids are an ideal candidate to act as a memory and interface with superconducting qubits due to their long coherence times. We spectroscopically investigate erbium-167-d…
Cavity enhanced Raman heterodyne spectroscopy in Er:YSO for microwave to optical signal conversion
Xavier Fernandez-Gonzalvo, Sebastian P. Horvath, Yu-Hui Chen +1
The efficiency of the frequency conversion process at the heart of Raman heterodyne spectroscopy was improved by nearly four orders of magnitude by resonant enhancement of both the…
