The APS annual DAMOP meeting is here! Weikun gives a contributed talk and poster on our defect-free 225-atom arrays, while Luheng presents a poster on the sodium experiment.
Controlling single atoms and molecules
With single quantum state resolution
Welcome to Loh Lab @ CQT
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.
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
D1 magic wavelengths are theoretically predicted to exist for the alkali atoms but have not been observed before. We experimentally confirm a D1 magic wavelength and use it to demonstrate an order-of-magnitude increase in the scalabilty of atom arrays, a fast-rising platform for quantum simulation and quantum computation.
