Research Scientist – QKD Implementation Security
Outline
Toshiba Europe Limited has been at the forefront of quantum communication for over a decade, pioneering technologies that set new standards in cryptography and data security. Our research underpins deployed Quantum Key Distribution (QKD) systems and continues to drive innovation in next‑generation quantum‑secure networking.
We invite applications for the post of Research Scientist in QKD Implementation Security at the Cambridge Research Laboratory, Toshiba Europe Ltd. This role focuses on the in-depth experimental characterisation and testing of QKD systems and components, developing a deep understanding of real system behaviour, device imperfections, and security‑relevant implementation details. The insights generated through this work directly inform system design, security analysis, and the evolution of deployed and future platforms.
Key Responsibilities
You will play a key role in the experimental characterisation of QKD systems, contributing high‑quality data and physical insight.
System Characterisation & Testing
* Design and carry out experimental tests of QKD transmitters, receivers, and subsystem components.
* Characterise photonic and electronic elements such as sources, detectors and modulators.
Implementation Security
* Generate experimental evidence that supports security analysis, modelling, and mitigation strategies.
* Provide clear, data‑driven input to decisions on system architecture and performance trade‑offs.
Collaboration & Contribution
* Work closely with experimental and theoretical teams to ensure security assumptions reflect practical implementation details.
* Contribute to joint research activities with academic and industrial partners.
* Write internal reports, co‑author scientific publications, and present work at conferences.
* Contribute to efforts to develop global standards for quantum technologies.
Skills & Experience (Essential)
* PhD (or equivalent experience) in Experimental Physics, Photonics, Electronic Engineering, or a related field.
* Strong hands‑on experience with experimental photonic systems.
* Proven ability to design, execute, and interpret complex measurements.
* Excellent written and verbal communication skills.
* Ability to operate effectively in a collaborative, multidisciplinary research environment.
Desirable Experience
* Knowledge of QKD, quantum optics, or quantum communications.
* Familiarity with implementation security or assurance‑driven testing.
* Experimental automation, data analysis, or system‑level testing experience.
* Experience with QKD systems or closely related platforms.
* Experience with electronics design (PCB development, FPGA programming, high‑speed electronics).
* Competence in Python or similar languages; experience with version control (e.g., Git)
Why Toshiba?
At Toshiba’s Cambridge Research Laboratory, you’ll combine the rigour of academic‑style experimentation with the impact and stability of a global technology leader. You’ll be part of a close‑knit team where detailed experimental insight directly shapes the future of secure quantum communications.
If you are motivated by hands‑on experimentation, deep system understanding, and translating careful measurement into real‑world impact, we would be delighted to hear from you.
