This Friday, 29th March, Physics Colloquium will be hosting Dr Jacquiline Romero, Quantum Physicist at UQ and the recent recipient of UNESCO International Rising Talent Award 2019. She will be discussing on her work related to Quantum Information using Transverse Spatial modes of Light. All are welcome!

Abstract. High-dimensional quantum information using the shape of light has moved to the mainstream over the last few years. In this talk, I will provide a brief background of quantum information using the transverse shape of light. I will then focus on two experiments that demonstrate what is possible with higher dimensions. The first is a demonstration of the statement “ignorance of the whole does not imply ignorance of the parts”. For example, being ignorant of a whole book implies that one is ignorant of at least one of its chapters. We show that despite ignorance of the whole book, there is no test that can reveal the chapter that one is ignorant of. The second experiment serves as a word of caution when one is working with higher dimensions, we show an experiment that apparently violates the Bell inequality beyond the Tsirelson bound.

Bio. Dr Jacquiline Romero was born and bred in Manila. She holds BS Applied Physics magna cum laude and MS Physics degrees from the University of the Philippines. In 2008, she decided the sun is a small price to pay for a chance to pursue her interests in quantum physics. She moved to Scotland and pioneered the use of spatial light modulators (SLMs) for single-photon measurements during her PhD at the University of Glasgow. She explored both experimental and theoretical aspects of entanglement of spatial modes related to optical orbital angular momentum. Missing the sunshine, she moved to Brisbane in 2015 to work in the Quantum Technology Lab with Prof. Andrew White at the University of Queensland, where she is currently an ARC Discovery Early Career Research Fellow. She continues her mission to extend quantum information using the transverse spatial modes of light.
