Entangled particles have always fascinated physicists, as measuring one entangled particle can result in a change in another entangled particle, famously dismissed as “spooky action at a distance” by Einstein. By now, physicists understand this strange effect and how to make use of it, for example to increase the sensitivity of measurements. However, entangled states are very fragile, as they can be easily disrupted by decoherence. Researchers have already created entangled states in atoms, photons, electrons and ions, but only recently have studies begun to explore entanglement in gases of polar molecules.

For the first time, researchers can turn on an electric field to manipulate molecular interactions, get them to cool down further, and start to explore collective physics where all molecules are coupled to each other.

The Micius Quantum Prize recognizes significant scientific advances ranging from the early conceptual contributions to the recent experimental breakthroughs. The Micius Quantum Prize 2020 focuses on the broadly defined field of quantum metrology, recognizing scientific advances ranging from early conceptual contributions to experimental breakthroughs. The laureates this year are Carlton Caves, Hidetoshi Katori, and Jun Ye.

Building on their newfound ability to induce molecules in ultracold gases to interact with each other over long distances, JILA researchers have used an electric “knob” to influence molecular collisions and dramatically raise or lower chemical reaction rates.

Older atomic clocks operating at microwave frequencies have hunted for dark matter before, but this is the first time a newer clock, operating at higher optical frequencies, and an ultra-stable oscillator to ensure steady light waves have been harnessed to set more precise bounds on the search.

JILA fellow Jun Ye has been named Highly Cited Researcher for 2020 by Clarivate Analytics. Ye has been awarded the Highly Cited Researcher in the field of physics every year since 2014.

SU(N) fermion systems are multi-component, spin-symmetrical collections of atoms—which are unique among degenerate gases. The Ye Group found that SU(N) fermion systems display special properties that allow them to be quickly cooled and prepared for use in quantum-matter based atomic clocks.

Quantum science has the potential to further revolution technology in several fields, from computing to communication. As a world-renowned leader in the field, JILA Fellow Jun Ye will advise U.S. leaders on ways to bring these advances out of the lab and into real-world applications.

A new national quantum research center draws on JILA Fellows' and their expertise to make the United States an international leader in quantum technology.

JILA Fellow Jun Ye will head new science and engineering institute to bring quantum discoveries out of the lab and into real-world applications.
