"Indistinguishable Photons From Defects in Diamond," by Lilian Childress, McGill University (Physics Colloquium Series)

Lilian Childress is an assistant professor in the physics department at McGill University.

Abstract: Individual defects in the diamond crystalline structure have properties akin to isolated trapped atoms or ions. Like atomic systems, defect centers can have spin degrees of freedom and and optical transitions that make them an attractive platform for building quantum information technologies. Diamond defect spins might someday be used to store and manipulate quantum information, and optics can play an important role in connecting defects into a useful computational network. An essential element of this vision is the possibility for different defects to emit identical photons--photons that could not, even in principle, ever be distinguished. This talk will introduce the NV defect center in diamond in this context, and describe a recent experiment probing the indistinguishability of photons emitted by different NV centers.
