    Website Cambridge Quantum Computing

    Cambridge Quantum Computing (CQC), is dedicated to developing and deploying advanced scientific research to lead us into the quantum age. CQC’s mission is to develop the world’s best quantum-based products and to make meaningful impacts on humanity.

    Location: Teddington and/or central London (Currently home working within UK – flexible working available)

    Cambridge Quantum Computing (CQC) is dedicated to advanced scientific research and currently employs in excess of 100 people and over 70 scientists. With research teams focused on quantum software, quantum chemistry, quantum natural language processing, quantum machine learning and quantum cryptography, our objective is to develop the best products to lead us into the quantum age.

    CQC has developed a range of technologies and recently launched the first self-testing quantum random number generator based on quantum correlations.   This is currently implemented on quantum computers and also, in the future, on a single-purpose device.  Deployment of this technology in the cryptography space is paving the way for new levels of information security.

    About the role
    As a researcher in theoretical cryptography you will work in our quantum cryptography team, which combines expertise in different fields such as quantum information and cryptography, mathematics and experimental physics in order to develop quantum-based solutions to problems in cryptography (see [1] for a sample of our work). Our team also works closely with the optics and engineering teams for the real-world implementation and deployment of our products.

    In this role you will bring your expertise in computer science and/or classical cryptography to find solutions to the different problems faced both by classical cryptography in a post-quantum world but also the ones faced by quantum cryptography. One such example is randomness extractors [2], which are both essential in quantum cryptography and also need to be made quantum-proof [3]. To thrive in this role you will be self-driven and given the freedom to learn, but you will also give direction and explore your own solutions to all these challenges.
    In summary, you will:

    • Research and design new cryptography applications with a quantum advantage, together with their security proofs.
    • Find innovative solutions to the problems faced by classical cryptography in a quantum world and to the challenges faced in quantum cryptography.
    • Develop and implement mathematical schemes and algorithms, e.g. randomness extractors, digital signatures and other cryptographic primitives.

    Key Requirements

    • Theoretical background in computer science and/or cryptography.
    • PhD in Computer Science, Mathematics, Physics or related field (or equivalent experience).
    • Familiarity with quantum cryptography, quantum-based and/or post-quantum.
    • Good programming skills (E.g. Python, C/C++ and/or other).
    • Capacity and desire to work in an interdisciplinary team.

     

    Desirable Skills

    • Job experience in research, either as a postdoc or with a company, is beneficial but not essential.
    • Track record of publications in relevant fields.
    • Ability to mentor and coach colleagues.
