Millisecond electron spin coherence time for erbium ions in silicon
Ian R. Berkman, Alexey Lyasota, Gabriele G. de Boo +12
Spins in silicon that are accessible via a telecom-compatible optical transition are a versatile platform for quantum information processing that can leverage the well-established…
Effect of a hybrid transition moment on Stark-modulated photon echoes in Er:YSiO
Rose L. Ahlefeldt, Alexey Lyasota, Jodie Smith +2
The 1538 nm I - I transition of Er has an unusual hybrid electric-magnetic dipole character, and signatures of the hybrid moment can be expecte…
Photoionization detection of a single Er ion with sub-100-ns time resolution
Yangbo Zhang, Wenda Fan, Jiliang Yang +11
Efficient detection of single optical centers in solids is essential for quantum information processing, sensing, and single-photon generation applications. In this work, we use ra…
Optimising the Efficiency of a Quantum Memory based on Rephased Amplified Spontaneous Emission
Charlotte K. Duda, Kate R. Ferguson, Rose L. Ahlefeldt +2
We studied the recall efficiency as a function of optical depth of rephased amplified spontaneous emission (RASE), a protocol for generating entangled light. The experiments were p…
Negative refractive index in dielectric crystals containing stoichiometric rare-earth ions
Matthew C. Berrington, Henrik M. Rønnow, Matthew J. Sellars +1
We investigate the prospect of achieving negative permittivity and permeability at optical frequencies in a dielectric crystal containing stoichiometric rare-earth ions. We derive…
The Zeeman and hyperfine interactions of a single ion in Si
Jiliang Yang, Wenda Fan, Yangbo Zhang +10
Er-doped Si is a promising candidate for quantum information applications due to its telecom wavelength optical transition and its compatibility with Si nanofabrication technologie…
