Job Summary
In this role, you will develop security proofs for practical QKD systems, analyze threat models, and adapt them for various protocols such as prepare-and-measure and entanglement-based schemes.
Your role in the team
- As a Senior Quantum Cryptography Expert, you will take a leading role in the development, analysis, and adaptation of security proofs for practical QKD systems.
- Your work will focus on understanding implementation details, identifying the relevant assumptions and threat models, and translating these into rigorous security statements using modern proof techniques.
- You will work across a broad range of discrete-variable QKD protocols, including both prepare-and-measure and entanglement-based schemes.
- Develop and adapt security proofs for practical implementations of QKD systems.
- Analyze implementation details, assumptions, and imperfections, and map them into appropriate proof models and security statements.
- Follow and evaluate the current state of the art in QKD security proof techniques, including advances in the literature.
- Work on security analyses for both prepare-and-measure and entanglement-based QKD protocols.
- Independently identify suitable proof strategies for new protocol variants, implementation settings, or certification-driven questions.
- Contribute to internal research and, where appropriate, to scientific publications in the field of QKD security.
- Collaborate closely with colleagues working on theory, implementation, and secure-key-rate analysis.
- Support the translation of proof assumptions and conclusions into forms usable for system development, security evaluation, and technical documentation.
- Help shape the company’s long-term expertise in QKD security theory and implementation-aware security analysis.
