On-demand Generation of Non-Gaussian Quantum Light from Exciton Polaritons

Description

This project aims to overcome a fundamental barrier in quantum optics: the probabilistic nature of creating non-Gaussian quantum states of light. These states are an essential resource for fault-tolerant universal quantum computing and advanced quantum sensing, yet current methods rely on inefficient conditional measurements due to the weak optical nonlinearity of conventional materials.

This project will investigate a new approach using exciton-polaritons, hybrid light-matter quasiparticles. By exploiting the strong Coulomb interaction inherent in their matter component, we aim to access the strong nonlinearities required to generate non-Gaussian states deterministically (on demand).

This research bridges condensed matter physics and quantum optics to solve a fundamental problem in technology. Successful results will not only advance quantum computing architectures but also deepen our understanding of quantum thermodynamics and phase transitions in driven-dissipative quantum systems.

Desired background

A BSc in Physics, experience with quantum optics or photonics is desirable. The successful applicant would need to meet the Australian Government H1E standards and UNSW entry standards. Contact Eli Estrecho to discuss possibilities.
