“Entanglement-enhanced optical atomic clocks will have the potential to reach a better precision in one second than current state-of-the-art optical clocks,” says lead author Edwin Pedrozo-Peñafiel, a postdoc in MIT’s Research Laboratory of Electronics. The new setup can achieve the same precision four times faster than clocks without entanglement.

The atoms are correlated in a way that is impossible according to the laws of classical physics, and that allows the scientists to measure the atoms’ vibrations more accurately.

The researchers report today in the journal Nature that they have built an atomic clock that measures not a cloud of randomly oscillating atoms, as state-of-the-art designs measure now, but instead atoms that have been quantumly entangled. Now a new kind of atomic clock designed by MIT physicists may enable scientists to explore such questions and possibly reveal new physics. With better atomic clocks, scientists could also start to answer some mind-bending questions, such as what effect gravity might have on the passage of time and whether time itself changes as the universe ages. If atomic clocks could more accurately measure atomic vibrations, they would be sensitive enough to detect phenomena such as dark matter and gravitational waves. The best atomic clocks in the world keep time with such precision that, if they had been running since the beginning of the universe, they would only be off by about half a second today. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a constant frequency, like many microscopic pendulums swinging in sync. Atomic clocks are the most precise timekeepers in the world.

This program could create many of the critical technologies, components, and demonstrations leading to a potential future networked clock architecture.”Ī Proposers Day for interested parties is scheduled for February 3, 2022, via live webcast details and registration information are available at. If we’re successful, these optical clocks would provide a 100x increase in precision, or decrease in timing error, over existing microwave atomic clocks, and demonstrate improved holdover of nanosecond timing precision from a few hours to a month.

Tatjana Curcic, program manager in DARPA’s Defense Sciences Office, said of the ROCkN program: 'The goal is to transition optical atomic clocks from elaborate laboratory configurations to small and robust versions that can operate outside the lab.

Although the clocks developed under the program will not be quite as as the best optical clocks found in a lab, they will surpass current state-of-the-art atomic clocks in both precision and holdover while maintaining low SWaP in a robust package. If the satellites' GPS signals were jammed by an adversary, time synchronization would rapidly deteriorate and thereby threaten military operations.ĭARPA officials state that ROCkN will leverage DARPA-funded research from the last several decades that has seen demonstration of the world’s most precise optical atomic clocks. When announcing the ROCkN program, DARPA outlined a plausible scenario: High-tech missiles, sensors, aircraft, ships, and artillery all rely on atomic clocks on GPS satellites for nanosecond timing accuracy a timing error of mere billionths of a second can translate to positioning being off by a meter or more. Defense Advanced Research Projects Agency (DARPA) has announced its new Robust Optical Clock Network (ROCkN) program, which seeks to create low size, weight, and power (SWaP) optical atomic clocks that yield timing accuracy and holdover better than GPS atomic clocks and that can be used outside a laboratory.
