Biography
Exporting practical implementation and next-generation technologies for quantum communications.
Dr Donaldson is an Assistant Professor and Research Fellow funded by the Royal Academy of Engineering to explore practical optical ground receiver technology for satellite quantum communications. His broader research interests are primarily associated with quantum communication technologies and their roll-out into practical service. This interest stems from his previous work on next-generation quantum communications technologies, including quantum digital signatures, quantum amplification, and single-photon array detectors.
His research team focuses on; quantum optical receivers for satellite QKD, practical implementation (1st gen service), high-bandwidth (next-gen service), and addressing background noise from natural (daytime) and artificial (jamming) in free space.
He is a co-investigator in the National Quantum Communications Hub, where he leads the Hub's Optical Ground Station (HOGS) design, development and operation for their In-orbit demonstrator mission. Beyond the Hub, He has connections to other UK-funded satellite QKD missions. In addition to scientific research, he has strong links to industry through five fully funded Innovate-UK Industrial Strategy Challenge Fund projects, enabling knowledge transfer.
