![]() Doing so won’t be any easier than many other challenges DARPA brings to the table, but the agency thinks advances in nanoelectromechanical systems (NEMS) resonators and nitrogen-vacancy (NV) centers in diamonds that exhibit single-atom-like properties could create a close analog to an atomic clock in a miniature, portable package. That’s why DARPA has put its feelers out for technology that could lead to portable atomic clocks that are miniature, ruggedized versions of the massive devices that keep standardized time in laboratories around the world.ĭARPA’s Quantum Assisted Sensing and Readout ( QuASAR) program aims to take high-performance atomic clocks like the National Institute of Standards and Technology’s NIST-F1, the massive room-sized clock housed in a lab in Boulder, Colo. DARPAs ROCKn program aims to make optical atomic clocks portable 3 1 Comment Like Comment Share LinkedIn Facebook Twitter David Carlton 5mo. However, a lack of coordinated clocks is a hindrance on the battlefield and elsewhere. DARPA's Robust Optical Clock Network (ROCkN) program would bring atomic clocks that are portable and small enough to fit inside military vehicles and satellites. When it comes to precision sensing, secure battlefield communications, and global positioning systems, DARPA knows what time it is.
