JILA Fellow and NIST Physicist Adam Kaufman Combines Multiple Atomic Clocks into One System

JILA Fellow and NIST (National Institute of Standards and Technology) Physicist and University of Colorado Boulder Physics professor Adam Kaufman and his team have ventured into the minuscule realms of atoms and…

A scale with two different cavities on it
To Measure or Not to Measure, but Dynamically Evolve—That is the Question

In the world of quantum technology, measuring with extreme accuracy is key.  Despite impressive developments, state-of-the-art matter-wave interferometers and clocks still operate with collections of independent…

Pulse sequences for generating two-axis twisting rotate the spins of KRb molecules, transforming the spin exchange interactions.
Polar Molecules Dance to the Tunes of Microwaves

The interactions between quantum spins underlie some of the universe’s most interesting phenomena, such as superconductors and magnets. However, physicists have difficulty engineering controllable systems in the lab…

Using an extremely high-powered laser, scientists can excite the thorium-229 nucleus, which is the core of a future nuclear clock.
Moving into a Nuclear Timekeeping Domain

An international team of researchers, led by JILA and NIST Fellow and University of Colorado Boulder Physics Professor Jun Ye and his team, has made significant strides in developing a groundbreaking timekeeping…

Bilayer crystals of trapped ions can be realized in devices called Penning traps, and lasers (shown in red and blue) can be used to manipulate the ions and engineer interactions between them. Such crystals may open new avenues for quantum technology applications.
A 3D Ion Magnet, the New Experimental Frontier for Quantum Information Processing

Many quantum devices, from quantum sensors to quantum computers, use ions or charged atoms trapped with electric and magnetic fields as a hardware platform to process information. 

However, current…

The lattice beams intersect Bose-Einstein condensed atoms (red) over the angled internal optic. Although only a single probe beam (blue) is shown, probe beams are aligned to each axis of the lattice to enable imaging from any direction.
Meet the JILA Postdoc and Graduate Student Leading the Charge in a Multi-Million-Dollar NASA-Funded Quantum Sensing Project

In the quiet halls of the Duane Physics building at the University of Colorado Boulder, two JILA researchers, postdoctoral research associate Catie LeDesma and graduate student Kendall Mehling, combine machine…
