Loh Lab

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!

Congratulations to Weikun for a fantastic PhD thesis defense! Weikun, best wishes for your postdoctoral fellowship at MPQ, and beyond!

Happy to be featured in the “Women of Quantum Technology” series in Inside Quantum Technology!

Our work on “Floquet-tailored Rydberg interactions” is published in Nature Communications and featured as a CQT highlight! Congratulations to Luheng, Michael, and Mujahid for their hard work!

Our lab takes part in the Institute of Physics Singapore annual meeting. Luheng gives an invited talk on Floquet frequency modulation with Rydberg atoms and Weikun gives a poster on Rb tweezer arrays.

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!

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.

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.

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.

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!

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.

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!

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.

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

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

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.
