Profile
Dr Hamid Tebyanian is a quantum physicist specialising in quantum communication and secure technologies. As a Marie Curie Fellow on the European project “Quantum Communication for All” at the University of Geneva, Vigo, and Padova, his research focused on developing practical quantum communication protocols to bring quantum technologies one step closer to users’ backdoors. At ID Quantique Switzerland, he worked on the design and fabrication of multimode fibre-coupled superconducting nanowire single-photon detectors (SNSPDs), addressing applications in quantum optics, single-photon imaging, and low-light-level detection. He subsequently contributed to a UK-wide project on the assurance of quantum random number generators, collaborating with 14 partners – including Toshiba and Quantinuum – to rigorously assess and validate the security of commercial QRNG devices. At the National Physical Laboratory, his research has concentrated on developing entanglement sources for experimental Bell inequality violations, with direct relevance to secure quantum communication. He is currently a lecturer at Queen Mary University of London, where his work bridges quantum science with advances in artificial intelligence, machine learning, and computing.

Research Interests:
Dr Hamid Tebyanian’s research interests span quantum cryptography, quantum communication, quantum optics, quantum foundations, and the integration of quantum technologies with AI and post-quantum cryptography. He develops secure quantum protocols, high-fidelity entanglement sources, quantum randomness generation techniques, and hybrid approaches that merge quantum and classical cryptographic methods.
In quantum cryptography, he investigates semi-device-independent and device-independent security frameworks, drawing on convex optimisation and information-theoretic analysis to validate quantum key distribution (QKD) and quantum random number generator (QRNG) devices under realistic conditions. This work has involved close collaboration with industrial and academic partners for practical deployment.
Within quantum communication, he designs and implements entanglement-based protocols for secure networks. At the National Physical Laboratory, he worked on entangled photon pair sources tailored for Bell inequality violations, facilitating applications in device-independent cryptography. His research also examines entanglement’s role in hybrid quantum-classical schemes and advanced security architectures.
In quantum optics, he has designed and characterised multimode fibre-coupled superconducting nanowire single-photon detectors (SNSPDs) for use beyond cryptography, including high-sensitivity imaging. He has also explored spontaneous parametric down-conversion and single-photon detection methods to enhance efficiency in quantum information processing.
His contributions to quantum randomness generation include novel protocols that address extracting provably secure randomness from quantum systems, implementing time-bin and continuous-variable schemes as well as incorporating orbital angular momentum and weak measurements.
In quantum foundations, his studies explore the impact of quantum gravity on Bell inequalities, the indistinguishability of quantum states, and paraconsistent logic in relation to quantum entanglement.
Beyond quantum cryptography, he has investigated hybrid security models by integrating post-quantum cryptography with quantum communication to develop robust frameworks resistant to both classical and quantum adversaries. His recent research applies machine learning to QRNG security assessments to create robust certification standards for practical cryptographic deployments.
