Abstract:
Point defects in diamond are atomic-like
systems embedded in a solid matrix. This
combination enables the manipulation of light
through light-matter interactions, as with
isolated atoms, in addition to enabling spatial
manipulations using photonic structures
embedded into the solid matrix. Specific
examples include sources of quantum light,
linear optical quantum gates, and quantum-
optical memories (QOMs). In this talk I will
focus on QOMs. These are key elements for the
scaling-up of optical quantum information
processing (OQIP), useful for both repeat-until
success schemes of quantum computation, and
for the synchronization of multiple photon
events for the creation of large-scale quantum
states of light, a required resource for OQIP. I’ll
present our work towards the use of an
ensemble of point defects in diamond for the
controlled storage of quantum light. Based on
previous work with atomic ensembles, I’ll
explain the principles of such QOMs, and the
adaptations needed for their implementation
with two types of diamond defects. I’ll then
present preliminary experimental results
towards this goal.
