A Magic Balance in Optical Lattice Clocks

Local interactions in the same lattice pull clock frequency negative while interactions between atoms on neighboring lattice sites pull clock frequency positive. By adjusting the atomic confinement, or tightness, of the lattice, researchers can balance these two counteracting forces to increase clock sensitivity.

Seeing Quantum Weirdness: Superposition, Entanglement, and Tunneling

Long-lived entangelement of Bell state pairs compared to single unentangled atoms in a 3D optical lattice. The Bell state "stopwatch" ticks twice as fast than that of a single atom, holding the promise of higher stability and higher bandwidth for optical clocks.

JILA and NIST Researchers Develop Miniature Lens for Trapping Atoms

Graphical illustration of light focusing using a planar glass surface studded with millions of nanopillars (referred to as a metalens) forming an optical tweezer. (A) Device cross section depicts plane waves of light that come to a focus through secondary wavelets generated by nanopillars of varying size. (B) The same metalens is used to trap and image single rubidium atoms.

Connecting Microwave and Optical Frequencies through the Ground State of a Micromechanical Object

The transducer developed by the Lehnert and Regal research groups uses side-banded cooling to convert microwave photons to optical photons

New Research Reveals A More Robust Qubit System, even with a Stronger Laser Light

An illustration of the efficient and continuously operating electro-optomechanical transducer whose mechanical mode has been optically sideband-cooled to its quantum ground state. This is the tool that will be used to convert microwave photons into optical photons to eventually send quantum signals over long distances.

About Our Sponsor: The National Science Foundation (NSF)

Physics Frontiers Centers (PFCs)

NSF logo.The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public. Read more about this program at the NSF website.
