Toshiba Europe Ltd have been at the forefront of research in quantum technology, particularly quantum communications and quantum key distribution (QKD) for the past two decades.  During this time they have made many breakthroughs, such as record high quantum communication bit rates, operation over very long fibres and multiplexing with conventional optical signals in fibre networks, achieving classical-quantum network integration.  Recently, Toshiba launched a new business unit to commercialise research outcomes and Toshiba QKD systems are now deployed in telecommunication networks across the world. 

We invite applications for a Research Scientist position at the Cambridge Research Laboratory, working in the area of next-generation fibre-optic quantum communication systems with significantly enhanced performance and new functionality.  The successful candidate will join a dynamic team and play a significant role in developing new quantum communication technologies, leveraging ideas across the fields of quantum, optics, electronics and communications to design, conduct and analyse frontier quantum experiments. Research outcomes will be published in leading academic journals and presented at international conferences, as well as supporting Toshiba’s QKD product development.


  • Devising new schemes for quantum communications and QKD
  • Building optical systems including lasers, modulators, detectors, optical fibres etc. and interfacing with high-speed RF electronics
  • Designing and implementing software to control experimental set ups and to simulate optical/quantum systems
  • Analysing experimental data
  • Writing scientific papers, reports and design notes
  • Delivering technical presentations, internally and internationally
  • Communicating with collaborators in the UK, Europe and Japan
