Dr Raj B. Patel

Adjunct Research Fellow

I am an experimental physicist interested in the physical implementation of quantum information protocols, in particular, quantum computing using photons. My previous work has been multidisciplinary, drawing expertise from various fields such as semiconductor physics and fabrication, microscopy, low-temperature physics, photonics, optics, and quantum optics. In the past, my work has focused on developing electrical sources of single photons based on semiconductor quantum dots.

My current research interests include implementing optical quantum logic using solid-state and heralded single-photon sources, coherent spin control in quantum dots, integrated photonics, meta-materials, quantum information, and quantum foundations.

At present, I am a senior researcher in quantum technologies and team leader of the quantum photonics sub-group in Professor Ian Walmsley's Ultrafast Quantum Optics group and the Networked Quantum Information Technologies hub at the University of Oxford.
