Quantum Optics describes research wherein one deals with light and its interactions at a microscopic/quantum level. This naturally brings us to the world of single photons which are the smallest particles of light. Our lab specialises in the manufacture and applications of single and entangled photons towards various applications in quantum technologies. While the other pages on our lab website discuss such applications, here we discuss quantum optics research which is at a fundamental level.
As a group, we are very interested in investigating Quantum Optical effects and phenomena, by pushing boundaries and extending known effects into the unknown realms. We study different effects like Hanbury-Brown-Twiss Interferometry, Hong-Ou-Mandel Effect as well as intricate nested interferometry using Mach Zehnder and Sagnac geometries for instance, to understand properties of different types of light with a very high accuracy. Our work in pure quantum optics deals with precise experimental as well as theoretical investigations, enabling many firsts in terms of discoveries.
