A Conveyor Belt MOT of Diatomic Molecules

Ultracold molecules provide a powerful and versatile platform for quantum computing,simulation, and metrology applications. The cornerstone technique for generating these cold, dense samples of molecular gasses is the magneto-optical trap (MOT). Conventional molecular MOTs use red-detuned light, limiting them to relatively high temperatures and low densities, leading to small spatial overlap and low loading efficiency...

Cavity-enabled real-time observation of individual atomic collisions

Arrays of individual neutral atoms represent a promising platform for quantum information processing due to their scalability, arbitrary connectivity, and long coherence times. These features are enabled in large part by the simple trapping and high-fidelity fluorescence imaging of individual atoms within tweezer traps. In our lab, we use strong dispersive coupling to a high-cooperativity...

Physicists arrange atoms in extremely close proximity

Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the particles are close. In many quantum simulators, scientists arrange atoms as close together as possible to explore exotic states of matter and build new quantum materials. They typically do this by cooling the atoms to a stand-still, then using laser...

Technique could improve the sensitivity of quantum sensing devices

In quantum sensing, atomic-scale quantum systems are used to measure electromagnetic fields, as well as properties like rotation, acceleration, and distance, far more precisely than classical sensors can. The technology could enable devices that image the brain with unprecedented detail, for example, or air traffic control systems with precise positioning accuracy.

High-fidelity parallel entangling gates in atom arrays

Recently, neutral-atom arrays have emerged as a promising platform for quantum computing. Atom arrays are highly flexible and reconfigurable, allowing coherent control over hundreds of qubits and connectivity between any qubits in the array. The main outstanding challenge of using atom arrays has been to reduce errors in entangling operations, which rely on highly-excited atomic...

Scalable Quantum Memory Control in Photonic Circuits

In a study published in “Nano Letters,” MIT and MITRE researchers describe an important advance in controlling spin quantum memories in photonic circuits. Their paper, “Selective and Scalable Control of Spin Quantum Memories in a Photonic Circuit,” offers a new approach for individual-qubit control even when the system is “under-actuated” — i.e., the number of...
