Progress towards quantum networking and two-fridge entanglement purification using solid-state defects in nanophotonic cavities.

ORAL

Abstract

Silicon vacancy (SiV) centers in diamonds coupled to nanophotonic crystal cavities are a powerful platform that has been used for proof-of-principle demonstrations of efficient single-photon generation, memory-enhanced quantum communication, and optical entanglement of distinguishable emitters. By leveraging long spin coherences of SiV, high cooperativities in cavities, and on-chip scalability, this platform offers powerful tools for the practical realization of long-distance quantum networking. In this talk, I will report on our progress towards a long-distance memory-enhanced quantum communication experiment in the Boston-area quantum network, a collaboration between Harvard, MIT, and Lincoln Labs. In addition, I will overview our current effort towards entanglement purification between two distinct quantum nodes spatially separated by tens of meters and connected by fiber.
