Summary

 

Summary

Dr Alex S. Clark is a Royal Society University Research Fellow working on Organic Molecular Quantum Photonics. He heads the Quantum Nanophotonics Project in the Centre for Cold Matter, and is Work Package Leader on Interfaces in the EPSRC Programme Grant "Quantum Science with Ultracold Molecules (QSUM)." His current research interests lie in the use of molecules to build new quantum technology and explore quantum science, such as creating on-demand photon sources, quantum memories, photonic quantum gates, and hybrid interfaces to link disparate quantum systems. 

A Short History

Alex Clark received an MSc Degree in Physics from the University of Bristol in 2005 and in 2011 received his PhD degree in quantum photonics from the Centre for Quantum Photonics, also at the University of Bristol, UK.

He was engaged in many projects in the Centre for Quantum Photonics through his years there, most notably his work with photonic crystal fibres to generate photons in a variety of quantum states, the demonstration of a quantum controlled-NOT gate in optical fibre and the creation of multi-qubit cluster states using fibre devices. He has had successful collaborations with a number of other institutions including the University of Bath, Imperial College London and the University of Nice. He joined the Centre for Ultrahigh-bandwidth Devices for Optical Systems (CUDOS) group at the University of Sydney in 2011 and was Project Leader of the Quantum Integrated Photonics Project. His research has been published in a number of journals and he has presented his work at many international conferences on a variety of subjects. Alex is a member of the Institute of Physics, IEEE, SPIE, and the Optical Society of America. His research interests lie in the integration of photon sources and entanglement on chip, the building of cluster states in integrated architectures and the use of novel materials to generate, manipulate and process quantum information.

In March 2014 he was a Visiting Researcher in the Centre for Cold Matter at Imperial College London where he worked on the use of organic dye molecules to build photon sources and other enhanced quantum technology. In May 2015 he won a Marie Skłodowska Curie Research Fellowship to work in the Centre for Cold Matter leading a group of researchers on tailoring and enhancing the emission of dye molecules using nanophotonic structures. In 2017 he was awarded a prestigious Royal Society University Research Fellowship to pioneer a new field of Molecular Quantum Photonics.

Dr. Clark was awarded a Worldwide Universities Network Researcher Mobility Award in 2011, an ARC Discovery Early Career Researcher Award (DECRA) in 2013, a Marie Skłodowska Curie Research Fellowship in 2015, a Royal Society University Research Fellowship in 2017, and a number of other research grants. He sits on the committee of the IOP Quantum Optics, Quantum Information, and Quantum Control (QQQ) Group and is the Secretary of the OSA London Local Section.
