Optical clocks at sea.

ABSTRACT: Deployed optical clocks will improve positioning for navigational autonomy¹, provide remote time standards for geophysical monitoring² and distributed coherent sensing³, allow time synchronization of remote quantum networks^4,5 and provide operational redundancy for national time standards. Although laboratory optical clocks now reach fractional inaccuracies below 10^-18 (refs. ^6,7), transportable versions of these high-performing clocks^8,9 have limited utility because of their size, environmental sensitivity and cost¹⁰. Here we report the development of optical clocks with the requisite combination of size, performance and environmental insensitivity for operation on mobile platforms. The 35 l clock comb
