OneQuantum Philippines will host “Hiding Ignorance and Finding Knowledge: Adventures Using the Shape of Light” online on Aug. 20, 2022, at 10 a.m. (PST). Jacqueline Romero, senior lecturer and Westpac Research Fellow at the University of Queensland, will be the speaker.
Romero is a quantum physicist in the Australian Research Council Centre of Excellence for Engineered Quantum Systems at the University of Queensland, Australia. Her research expertise and interests are in the field of quantum foundations and quantum information. In particular, Romero is an experimental quantum physicist studying the properties of single photons for the development of new quantum alphabets and the nature of quantum causality.
Romero will discuss two recent experiments. The first is on ignorance: One might ask if ignorance of a whole system implies ignorance of its parts. Our classical intuition tells us yes, however quantum theory tells us no: it is possible to encode information in a quantum system so that despite some ignorance of the whole, it is impossible to identify the unknown part. She will give a piece of experimental evidence that supports this counterintuitive fact.
The second is on learning: We used a tomographic technique inspired by machine learning to track a quantum state as the state changes. The method is computationally efficient and also robust—it converges to a good estimate even in the presence of strong noise. Developing techniques like this is especially important for systems that are of high dimensionality, where making tomographically complete measurements become impractical.
OneQuantum Philippines is a local chapter of the OneQuantum global community. It aims to make the Philippines a quantum-ready nation by educating students at an early age so it would be easy for them to acquire quantum computing skills. For more information, visit OneQuantum Philippines.
