My research focuses on the development of photonic quantum technology and its application to experimental quantum information processing—from foundational research to quantum communication, computation and metrology. Quantum technology is now on the brink of delivering devices that can surpass the capabilities of their classical counterparts. Photonics plays a key role in this quantum revolution, providing a scalable quantum processing platform in its own right, but also due to its unique ability to coherently connect other physical architectures. My goal is to drive all facets of this development, from improving primary photonic capabilities to creating scalable hybrid quantum systems.

Dr Alessandro Fedrizzi joined Heriot-Watt University in September 2015 as an Associate Professor. He currently holds an EPSRC Early Career Quantum Technology Fellowship. Prior to moving to Heriot-Watt he spent seven years—including three on a ARC Discovery Early Career Award—as a research fellow with Andrew White at the University of Queensland, Australia. Dr Fedrizzi completed his PhD in 2008 under the auspices of Anton Zeilinger at the Institute for Quantum Optics and Quantum Information in Vienna.
