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.

Nov 2023

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!

Sep 2023

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.

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!

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.

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.

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.

Oct 2022

Fan Jia, who did his PhD in the group of Dajun Wang at the Chinese University of Hong Kong, joins us as a postdoc. A warm welcome to you, Fan!

Sep 2022

An gives an invited talk and Mujahid gives a contributed talk at the Institute of Physics Singapore (IPS) annual meeting.

Sep 2022

Our manuscript reporting a new algorithm to efficiently assemble large-scale defect-free atom arrays is now up on the arXiv! Our parallel sort-and-compression algorithm (PSCA) offers a reduced move complexity (only scaling as the square root of the target array size) and naturally avoids collisions between atoms. Here is a defect-free image of 225 singly-trapped atoms pristinely arranged in a triangular array, obtained by applying our new algorithm.
