Atomic Physics Seminar - Morgan Hedges, University of Calgary - "Progress Toward Ultra-Long Coherence Times for Rare-earth Ion Quantum Memory"
Rare-earth ions in the solid state are a prime candidate for quantum
memory and other quantum information applications, due to their strongly
shielded optical transitions. These same optical transitions allow for
direct optical manipulation of nuclear-spin transitions. This is of
interest for studying interactions in solids, as well as for long-term
storage of light in quantum memory applications. In this talk I'll discuss
experiments and early results to lengthen the coherence time of Europium
nuclear spins when doped into the host Y2SiO5. We are on track to improve
upon our group's earlier demonstration of seconds long light storage in
Pr:Y2SiO5 by around 2 orders of magnitude.
