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, seamless classical‑quantum network integration and the invention of new approaches for record long distances. 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 (or Senior Research Scientist, depending on experience) 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, including new protocols such as Twin‑Field QKD (TF‑QKD). The successful candidate will join a dynamic team and play a leading 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, alongside technology transfer to Toshiba’s quantum business division.
