Where Motion Meets Spin: A Quantum Leap in Simulating Magnetism

Molecules sparsely occupy a deep 3D optical lattice. Molecules interact with induced dipole moments and transition dipole moments represented by squiggly lines between lattice sites. Lowering the lattice depth in the horizontal direction allows tunneling between sites within layers.

Combining Machine Learning with Quantum Metrology: Making a Universal Quantum Sensor

Simulation using the gradiometer protocol

Quantum Teleportation Gets an Ionic 2D Upgrade

Teleporting quantum information stored in collective spin states of ions within a two-dimensional crystal

Making a Leap by Using “Another State to Entangle”

No Cavity, No Party: Free-Space Atoms Give Superradiant Transition a Pass

A pencil-shaped ultracold gas of frozen two-level atoms interacting via photon-mediated interactions, with elastic and inelastic components. A continuous laser drive excites the atoms on-resonance. Atoms also spontaneously emit photons into free-space.

To Measure or Not to Measure, but Dynamically Evolve—That is the Question

A scale with two different cavities on it

A 3D Ion Magnet, the New Experimental Frontier for Quantum Information Processing

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.

Meet the JILA Postdoc and Graduate Student Leading the Charge in a Multi-Million-Dollar NASA-Funded Quantum Sensing Project

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.

Twisting and Binding Matter Waves with Photons in a Cavity

Atoms inside of an optical cavity exchange their momentum states by "playing catch" with photons. As the atoms absorb photons from an applied laser, the whole cloud of atoms recoil rather than the individual atoms.
