Loh Huanqian Group

Advanced materials like superconductors have the potential to change energy transport as we know it. However, their dynamics on the microscopic scale remain poorly understood as they are difficult to simulate with classical computers. A promising solution is to assemble ultracold atoms and molecules as quantum building blocks to mimic these advanced materials and directly observe the dynamics in these clean systems.

Our lab focuses on the control of atoms and molecules at the single-particle, single-quantum-state level. To access this regime, we develop tools to precisely control the motion, internal quantum states, and spatial arrangement of individual particles held in reconfigurable optical tweezers. These versatile quantum lego blocks are in turn used for quantum simulation, allowing us to study interesting quantum materials in the laboratory while working towards building scalable quantum computers.

Huanqian Loh joined NUS as President's Assistant Professor at the Department of Physics and Principal Investigator at CQT in 2017. She leads a research group that aims to use optical tweezer arrays of atoms and molecules like reconfigurable quantum simulators to mimic advanced materials. She earned her PhD from the group of Eric Cornell at the University of Colorado Boulder.

For her research, Huanqian was recognized as a L’Oréal-UNESCO For Women in Science International Rising Talent in 2020, a World Economic Forum Young Scientist in 2019, and a Singapore National Research Foundation Fellow (Class of 2018). She also serves on the World Economic Forum Global Future Council for Quantum Applications.
