IonQ’s role is to advance its ability to produce the Evergreen-05 optical atomic clock by investing $15 million on production space, manufacturing equipment, testing capabilities and support staff. Deliverable production units are expected to be available within a year after the facility’s completion. Evergreen-05 is an optical atomic clock that works to deliver timing stability of 50 femtoseconds at one second and nanosecond holdover over 10 days. Evergreen-05 was originally developed under DARPA’s Robust Optical Clock Network program, which It’s About Time builds on. The atomic clock was prototyped by Vector Atomic, which was acquired by IonQ in October 2025.
