Quantum timekeeping is supposed to be the ultimate in efficiency, with tiny devices that tick using the rules of quantum mechanics instead of swinging pendulums or vibrating quartz. Yet new work on a ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Breakthroughs in the quantum space are coming fast, and threats once dismissed as speculative now seem inevitable. For industries that rely on trust and long-lived devices, the transition to ...

Physicists uncover a universal limit on timekeeping precision, proving that anything from heartbeats to ocean waves can be a ...

How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is ...

Microsemi Corporation introduced the release of its enhanced Quantum™ Rubidium Miniature Atomic Clock (MAC) SA.3X family. As one of the industry’s smallest, lightest and highest-performing MACs, the ...
