Atomic Clocks

Atomic clocks are oscillators providing a signal with exquisite frequency (and hence timing) stability, derived from ultra-stable alkali atomic transitions in a controlled environment. A miniature atomic clock (MAC) combines the advantages of reduced size, weight and power (SWaP) with superior timing accuracy over quartz-based technologies. MACs have the potential to improve the performance of secure telecommunication systems or Global Navigation Satellite System (GNSS) instruments.

Objective: in macQsimal, partners will work closely together to develop a Miniature Atomic Clock (MAC) prototype based on coherent population trapping (CPT) in 87Rb filled MEMS atomic vapor cells, with very low SWaP and costs and with exquisite long-term performances.
