Quantum optics and nanoscale sensing in diamond
Presented by Victor Acosta, Google Inc.
Color centers in wide-bandgap semiconductors offer a way to merge atomic physics and condensed-matter nanotechnology to engineer a new class of devices with tailored interactions in a scalable platform. The nitrogen vacancy (NV) center in diamond is a promising system due to its atom-scale electronic wavefunction, long-lived paramagnetic ground state, and spin-selective optical transitions even at room temperature.
Towards applications in information processing, I will discuss progress in fabricating nanophotonic networks containing spectrally-pure NV centers embedded in high-quality optical cavities as well as using electromagnetically-induced transparency with NV ensembles for few-photon nonlinear optics.
Towards applications in life sciences, I will discuss our recent work using nanostructured diamond devices for surface-enhanced nuclear magnetic resonance. Here we seek to hyperpolarize room-temperature liquids/gases and perform nanoscale MRI with wide-field optical readout.
Finally, I will highlight challenges with using NV centers, and discuss other emerging systems, including the Silicon-Vacancy center in diamond and defects in SiC, which have more favorable properties for certain applications.
