UPDATED: DARPA Selects IonQ to Produce Next-Generation Atomic Clocks

Under the DARPA It’s About Time program, IonQ will accelerate production and deliver 125 Evergreen-05 optical atomic clocks to U.S. government customers; this release is a clarification of the release issued earlier today

● IonQ has received a $28 million contract extension, with an additional option of $30 million through DARPA’s It’s About Time program.

● The company will invest $15million in dedicated production space, manufacturing equipment, testing capabilities and support staff.

● IonQ will deliver 125 atomic clocks to the U.S. government for mission-critical applications.

COLLEGE PARK, Md. – Aug. 6, 2026 - IonQ (NYSE: IONQ) clarifies its announcement that it has been awarded a $28 million contract extension, with an additional option of $30 million through the Defense Advanced Research Projects Agency (DARPA) It’s About Time program. Under the program, IonQ will advance its scalable clock production capabilities for its Evergreen-05 optical atomic clocks and deliver 125 units to U.S. government customers. The clocks are designed for mission-critical applications including radar, secure communications, and precision geolocation.

This $28 million award is a modification to its existing DARPA agreement, and this modification will cover manufacturing development and 25 Evergreen-05 clocks. A further $30million option, not yet exercised, would cover an additional 100 clocks, for a combined value of up to $58 million.

Originally developed under DARPA’s Robust Optical Clock Network program, IonQ’s Evergreen-05 is a compact, fully integrated optical atomic clock with a 5-liter, shoe box-sized form factor. It delivers timing stability of 50 femtoseconds at one second and nanosecond holdover over 10 days–projecting to a timing error of less than one second over30 million years.

● Compared with active hydrogen masers, Evergreen-05 delivers superior phase noise and short-term stability with comparable long-term drift.

● The clock provides this performance in 1/75th of the volume of an active hydrogen maser.

● Its tactical package and broader environmental operating range extend IonQ’s existing clock technology across land, maritime, and airborne platforms.

DARPA’s support for the core Evergreen-05 technology began in 2019, when it funded an initial effort for Vector Atomic, then a year-old startup in Pleasanton, California. IonQ acquired Vector Atomic in October 2025 to expand its capabilities into quantum position, navigation, and timing.

“We added Vector Atomic to the IonQ family because their clocks and sensors are the best in the world,” said IonQ Chairman and CEO Niccolo de Masi. “DARPA’s investment under the It's About Time program confirms that we made the right choice.”

“DARPA has been a partner every step of the way. That initial support was critical to prove the core concepts of our clock,” said Marty Boyd, director of IonQ’s timekeeping division and co-founder of Vector Atomic. “We joined IonQ to accelerate and scale up delivery of our commercial products, and DARPA's continued support gives us the opportunity todo that.”

To support Evergreen-05 delivery, IonQ will invest $15 million in dedicated production space, advanced manufacturing and test equipment, and support staff.
