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.

Aug 2023

Our collaborative paper with the group of Ching Hua Lee, on probing non-unitary phase transitions with Floquet-engineered Rydberg atom arrays, is published in Physical Review Letters! Congrats to Mujahid and all the co-authors!

Jun 2023

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.

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.

Jul 2023

Congratulations to Mujahid on his successful PhD thesis defense. What an exciting journey it has been for the past 5 years!

Jun 2023

Huanqian gives an invited talk at the ICMAT conference at the end of this month, while Weikun gives a poster at ICOLS in Colorado the same week.

Jun 2023

Honored to have Deputy Prime Minister Heng and Senior Minister Teo visit our lab. Happy to show them the atom-array setups that are the culmination of several years of hard work from my team, with valuable help from the CQT support staff.

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!

Feb 2023

Our lab is featured in a video that is sponsored by the Singapore Quantum Engineering Programme office and will be screened on the American Physical Society (APS) TV during March Meeting. (1:00) See Luheng, An, Weikun, and I checking out our homemade laser stabilization cavity housed in a vacuum chamber. Thanks to Alex, Jenny, and Xin Yi for spotlighting our research!

Jan 2023

Huanqian delivers several invited talks this month: at the Majulab seminar (thanks to Gabriel, Alexia, Nelly, and Christian), at the Workshop on Quantum Information Science with Cold Atoms (thanks to Jae-yoon, Jongchul, Eunmi, Jee Woo, and Gil Young), and at the Global Young Scientists Summit organized by NRF Singapore.

Jan 2023

Juan-Yi and Jintao join our group as undergraduate interns. Welcome on board!

Dec 2022

Time for an end-of-the-year group party. Best wishes for a productive 2023!

Dec 2022

Huanqian takes part in the NUS S&T Agora fireside chat on quantum technologies.

Nov 2022

We give two more lab tours this month: one to the NUS Board of Trustees and another to a delegation from the Ministry of Finance and the National Research Foundation.

Oct 2022

We are happy to host Emeritus Senior Minister Goh and Minister Josephine Teo (Ministry of Communications and Information) in two separate visits to our lab this month.
