With single quantum state resolution
Our lab at the Centre for Quantum Technologies, National University of Singapore, is interested in using arrays of tweezer-trapped atoms as quantum "lego" blocks to simulate advanced materials.
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 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.
Juan-Yi and Jintao join our group as undergraduate interns. Welcome on board!
Time for an end-of-the-year group party. Best wishes for a productive 2023!
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.
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.
