Huanqian Loh is a President’s Assistant Professor at the National University of Singapore and Principal Investigator at the Centre for Quantum Technologies. She is interested in advancing the scalable and programmable control of qubits for quantum simulation and computation. For her research, Huanqian has been recognized as a Singapore National Research Foundation Fellow in 2018, a World Economic Forum Young Scientist in 2019, and a L’Oréal-UNESCO For Women in Science International Rising Talent in 2020.


Scaling up atom arrays

Neutral atom arrays are a promising platform for the bottom-up control of individual qubits in a scalable and programmable way. These atom arrays host tunable interactions and can be arranged to form arbitrary geometries, making them attractive candidates for quantum computation and simulation. Scaling up atom arrays while maintaining high fidelity control would allow one to simulate larger and more complex quantum many-body systems. In this talk, I will discuss the limits of scaling up atom arrays and present two solutions to overcome these limits: the first involving a new class of “magic” wavelengths for optically trapping atoms, and the second involving a novel parallel rearrangement algorithm to rapidly assemble defect-free arrays of hundreds of singly-trapped atoms in real time. I will also discuss different routes for inducing programmable interactions between the singly-trapped particles, with an eye towards future quantum simulation studies.
