Enhanced Timekeeping with Optical Clocks

Presented by Robbie Fasano (Infleqtion)

Clocks based on optical transitions outperform microwave clocks by orders of magnitude, allowing sub-picosecond synchronization and enhanced holdover. This technology has the potential to transform fields ranging from fundamental physics to distributed computing, but has not yet been commercialized or deployed at scale. I present Infleqtion's efforts at development and commercialization of an optical clock based on a two-photon transition in rubidium vapor and outline a path towards mass production of chip-scale optical clocks. Beyond optical timekeeping, I will also discuss end-to-end optical time dissemination, a path towards synchronization of remote clocks at the femtosecond level.
