MajuLab Seminar by Timothy Liew – 11 May 2023

Thimothy Liew

Timothy Liew is an Associate Professor at Nanyang Technological University. His primary interest is in the field of exciton-polaritons, where he predicted the existence of
topological polaritons and the superbunching of bosonic cascades. Occasionally, his theoretical predictions have relevance to other fields, where his prediction of the
unconventional blockade was experimentally verified in quantum dot and superconducting circuit systems. He is also focused on finding potential applications of excitonpolaritons, where he has proposed their use as photonic neural networks in both the classical and quantum regimes.

Reservoir Computing with Nonlinear Optical Cavities

Reservoir computing is a simple neural network architecture supporting hardware friendly implementation in a variety of systems. Here we will explore the use of nonlinear optical cavities, such as those containing exciton-polaritons, as a foundation for implementation, where the potentially quantum optical nature of such systems may offer new opportunities for the processing of quantum information. In particular, it is understood that classical neural networks excel in the recognition of classical patterns, so it is natural to consider the use of quantum networks for the recognition of quantum patterns corresponding to the classification of quantum states or their tomography. It is also interesting to consider how such networks provide a platform for the generation of non-classical states.
