Research interests and activities

My research largely falls into the areas of integrated quantum photonics, quantum metrology, quantum walks and quantum information processing.

Prior to integrated quantum photonics, quantum optics consisted of individually aligned optics (e.g. lenses, fibres, mirrors) bolted onto ~3-ton optical isolation tables. Highlights of my early contributions to this field include manipulating quantum states of light in a microchip[Nature Photonics, 3, 346 (2009)] and first implementing a compiled version of a quantum algorithm on chip [Science, 325, 1221, (2009)]. More recent highlights from my group include a fully reconfigurable optical two-qubit processor [Nature Photonics 12, 534 (2018)] and demonstrating integration of quantum photonics with micro-electronics [Nature Photonics 15, 11 (2021)].

In quantum metrology we explore harnessing the unique properties of quantum mechanics to achieve precision beyond the physical limits of current technology. Recent highlights from my group in this field include devising optimal measurement of optical phase and loss [Phys Rev Lett, 124, 140501 (2020)], sub shot noise- microscopy [Optics Express 27 30810 (2019)], using bright squeezed light for quantum-enhanced precision estimation of loss [Phys. Rev. Applied 16, 044031 (2021)] and with collaborators in Nottingham, a genetic algorithm to automate quantum sensor design [Quant. Sci. Tech. 4, 045012 (2019)].

My research contributions have been recognized most recently by award of a Philip Leverhulme Prize for Physics (2021).
