The clock is the latest demonstration that a much more precise definition of the official second is possible and that new applications of clocks are feasible.
Opening new possibilities for quantum sensors, atomic clocks and tests of fundamental physics, JILA researchers have developed new ways of “entangling” or
Physicist Jun Ye has a knack for making every second count—literally. At JILA, a joint research institute of the University of Colorado and the National
JILA researchers have upgraded a breathalyzer based on Nobel Prize-winning frequency-comb technology and combined it with machine learning to detect SARS-CoV-2
A team of researchers at JILA has for the first time successfully combined two of the “spookiest” features of quantum mechanics to make a better quantum sensor.
Atoms are notoriously difficult to control. They zigzag like fireflies, tunnel out of the strongest containers and jitter even at temperatures near absolute
Before we can send bits of information through networks of quantum computers at different locations, we need to resolve an issue with our building blocks for
Gone are the days of bucket brigades for firefighting — long lines of people passing buckets of water one at a time toward a blaze — but NIST/JILA researchers
JILA physicists have measured Albert Einstein’s theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever
JILA researchers have tricked nature by tuning a dense quantum gas of atoms to make a congested “Fermi sea,” thus keeping atoms in a high-energy state, or
JILA scientists have boosted the sensitivity of their decade-old frequency comb breathalyzer a thousandfold and can detect additional biomarkers of disease —
In a significant advance toward the future redefinition of the international unit of time, the second, a research team led by the National Institute of
Look out dark matter, here come the detectives. This NIST amplifier, which measures tiny electrical currents, has boosted the search for the mysterious dark
JILA physicists have boosted the signal power of their atomic “tweezer clock” and measured its performance in part for the first time, demonstrating high
Building on their newfound ability to induce molecules in ultracold gases to interact with each other over long distances, JILA researchers have used an
JILA researchers have developed tools to “turn on” quantum gases of ultracold molecules, gaining control of long-distance molecular interactions for potential
JILA researchers have used a state-of-the-art atomic clock to narrow the search for elusive dark matter, an example of how continual improvements in clocks have
JILA physicists and collaborators have demonstrated the first next-generation “time scale” — a system that incorporates data from multiple atomic clocks to
