Marco Lucamarini
Chair - Experimental Quantum Communications & Director of Research - York Centre for Quantum Technologies Professor



Professor Lucamarini joined the University of York in 2020, coming from a senior position in Toshiba’s Cambridge Research Laboratory, where he conducted research into optical physics, quantum information and quantum key distribution (QKD), bringing the UK’s first quantum network into existence.

In 2018, he was instrumental in leading a breakthrough which marks the beginning of a quantum repeaters era. The novel scheme, termed 'Twin-Field QKD', can extend the range of QKD to well over 500 km when applied down standard optical fibre and beyond 100 dB in a lossy quantum channel. This makes quantum secure communications on fibre links between geographically dispersed cities possible for the first time.

Prior to that, he worked at a number of universities and institutions contributing to pioneering experiments such as the active quantum teleportation of a photon, the open-loop protection of a polarization qubit and two-way protocols for QKD.
