PhD Studentship in Quantum Cryptography

The Department of Mathematics at King's College London is offering a fully-funded PhD studentship in Quantum Cryptography under the supervision of Prof. Roger Colbeck. The aim of this field is to exploit the properties of quantum systems to enable provably secure communication. The project will study the theory behind device-independent quantum cryptography, which exploits Bell inequality violations to further enhance security. One of the main aims will be to develop new protocols (together with security proofs) that enable device-independence to work with increased practicality and on real-world devices, hence pushing this technology closer to commercialisation. The work will be connected to EPSRC's Integrated Quantum Networks Hub, a multimillion pound, UK-wide project within the UK Quantum Technologies programme. The successful candidate will be connected to this project and hence have the opportunity to interact with a wider UK community developing and exploiting quantum networks. The anticipated start date of the studentship is 1st October 2026.
