A collaborative research effort has brought the world closer to creating a nuclear clock by precisely exciting scandium-45 with X-ray pulses. This marks a significant…
Illustration of the laser interrogation of a highly charged ion clock (artwork). Credit: PTB The scientists of the QUEST Institute at PTB have developed and…
A new technique to measure vibrating atoms could improve the precision of atomic clocks and of quantum sensors for detecting dark matter or gravitational wavesGravitational…
University of Wisconsin–Madison physicists have made one of the highest performance atomic clocks ever. Their instrument, known as an optical lattice atomic clock, can…
JILA physicists have measured Albert Einstein’s theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that…
Mismatched partners are being cooled: A single beryllium ion (red, left) and a single highly charged argon ion (purple, right) are bombarded by lasers from…
An atom laser flowing from top to bottom makes a “caustic,” a refracted pattern like that often made by light, as it encounters an obstacle.…
NASA’s Deep Space Atomic Clock has been operating aboard the General Atomics Orbital Test Bed satellite since June 2019. This illustration shows the spacecraft in…
Atoms are trapped in an optical cavity composed of two mirrors. When a “squeezing” laser is set through the cavity, the atoms are entangled, and…

The Deep Space Atomic Clock may change the way spacecraft navigate in space. Descendants of the technology demonstration could be a key component of a…
The clock is ticking: A technology demonstration that could transform the way humans explore space is active. Developed by NASA’s Jet Propulsion Laboratory in Pasadena,…
JILA/NIST physicist Adam Kaufman adjusts the set-up for a laser that controls and cools the strontium atoms in the optical tweezer clock. The atoms are…
NASA’s Deep Space Atomic Clock (DSAC), the first GPS-like technology for deep space, started its one-year space mission on Friday, August 23, 2019. If the…
