Loh Lab is moving to Duke in Fall 2024!

Our lab is interested in using arrays of tweezer-trapped atoms as quantum "lego" blocks to simulate advanced materials and to process quantum information.

Understanding our research focus

Quantum simulation is the modeling of nature with quantum building blocks like atoms and molecules.

Quantum simulation allows us to study interesting quantum materials while working towards building powerful computers.

Arrays of optical tweezers provide a powerful platform for controlling individual quantum building blocks in a scalable manner.

Atoms, molecules, lasers, microwaves, electric fields, magnetic fields, some epic code, and a huge dose of fun!

Our research highlights

Our team develops new methods to scale up and program atom arrays, a promising platform for quantum computation and simulation. Our latest results include: (1) demonstrating a new parallel atom-rearrangement algorithm, with which we achieved large defect-free arrays with hundreds of singly-trapped atoms in arbitrary geometries; (2) realizing Rydberg-blockade entanglement beyond the blockade radius for atom arrays with improved qubit connectivity.

News Updates

We are moving to Duke!

We are relocating to Duke University in Fall 2024. Our lab will be located at the Duke Quantum Center. We are looking for talented and motivated students to join us at Duke.

Put a quantum system in a far-from-equilibrium state, and it should either thermalize or retain memory of its initial state – at least that’s what scientists have always thought. Can thermalization and memory occur simultaneously? Read our arXiv paper to find out what surprises we have uncovered with our Rydberg-atom quantum simulator!

Our Floquet frequency modulation manuscript is up on the arXiv! We report using Floquet frequency modulation to advance atom arrays on three fronts: 1. achieve Rydberg-blockade entanglement beyond the traditional blockade radius; 2. extend the coherence of entangled states; 3. realize new ways to initialize strongly-interacting states.

Jun 2023

Time for our group to travel to the US for conferences again! At the annual APS DAMOP meeting, Michael and Fan give talks and posters, while Huanqian delivers an invited talk. Luheng presents at the Gordon Research Conference (Atomic Physics). Thanks to everyone in the community for their positive comments and helpful feedback!

Mar 2023

Our work on achieving large (225-atom) defect-free arrays with a high success probability is now published in Physical Review Applied and featured in the APS Physics magazine! Very satisfying to see the Singapore lion head symbol appear in a Physical Review journal. Congrats to Weikun, Wen Jun, An, Billy, Raj, and Vanessa for their hard work! See also these highlights of Wen Jun and of our work on NUS news, Phys.org, and the CQT homepage.
