Spin, Photons and Phonons: Diamond Nanophotonics

Explore a 47-minute lecture by Paul Barclay from the University of Calgary, presented at the Institute for Quantum Computing, examining the fascinating world of diamond nanophotonics. Discover how defects in diamond serve as a promising platform for quantum information processing and sensing, with particular focus on coupling electron spins using mechanical resonators. Learn about phonons in engineered nanomechanical devices that exhibit exceptionally long coherence times and can be coupled to various physical systems. Understand how integrating nanomechanical resonators within optical cavities creates cavity optomechanical devices that enable optical control of mechanical motion. The lecture covers recent demonstrations of spin-phonon driving in diamond cavity optomechanical devices, resulting in a "universal" spin-photon interface that functions independently from the optical properties of the spin system. Additionally, examine recent discoveries in nonlinear optics related to the microscopic properties of diamond defects.
