Toshiba Quantum Communications Technologies
Toshiba has been at the forefront of quantum communications technologies for over two decades, particularly in quantum cryptography and networking. Toshiba’s commercial quantum key distribution systems offer the highest key rates on the market and play a major role in the worldwide deployment of secure quantum networks.
Photonic integrated circuits (PICs) have revolutionized photonic technologies such as coherent optical communications, sensing, and computing. Over the past decade, their application to quantum technologies has been a strong catalyst for the miniaturisation and scalability of quantum systems, enabling compact, high-performance devices that are viable for commercialisation.
We invite talented researchers with expertise in photonic integrated circuits (PICs) and quantum technologies to join our Photonic Integration Team at Toshiba Europe’s Cambridge Research Lab. The successful candidate will lead the development of cutting-edge photonic integrated circuits for next-generation quantum communications and networking systems. The role spans from the conception of the photonic chips to their validation and integration in deployable system prototypes.
The ideal candidate will have a strong background in photonic integrated circuits and/or quantum technologies, with a proven track record of delivering high-impact research, the motivation to lead challenging research and development projects in a multidisciplinary environment, and the ability to work effectively with internal and external collaborators in a multidisciplinary environment. Research outcomes will be published in leading peer-reviewed scientific journals and presented at major international conferences. Technology developments will directly contribute to Toshiba’s roadmap for the marketisation of chip-based quantum communications products.
