The Royal Navy and MSubs tested Infleqtion’s Tiqker optical atomic clock aboard an autonomous submarine — the first deployment of its kind. A breakthrough for GPS-free navigation and quantum sensing in real-world conditions.

Infleqton aims to reduce both the size and cost of Tiqker by 50%, which should open up commercial sectors, as Max Perez explains on MoveTheNeedle.news:

Schrödingers Katze verbessert Atomuhren

Quantenmechanik trifft Zeitmessung: Physiker haben Atome so manipuliert, dass sie genauer und schneller "ticken" als gängige optische Atomuhren. Möglich

Move Over Cesium Clock, Optical Clocks Are Taking Over

We normally think of atomic clocks as the gold standard in timekeeping. The very definition of a second — in modern times, at least — is 9,192,631,770 periods of the radiation correspon…
