Research Interests

My primary research interests are in the fields of Quantum Cryptography, Quantum Computation and Quantum Information Theory. A list of topics that I am working:

- Quantum-Key-Distribution and Quantum-Digital-Signatures. Security and Implementations
- Device Independent Quantum Cryptography
- Blind Quantum Computation and Secure Multiparty Quantum Computation
- Verification of Quantum Computation and of Quantum Technology
- Alternative models of Quantum Computation
- Properties of Quantum Mechanics for Quantum Information Tasks. Quantum non-locality and   optimal quantum measurements.

In the past I have also worked on the Foundations of Quantum Mechanics and Quantum Gravity.


BSc in Physics with Theoretical Physics, Imperial College London 2002.

Master of Advance Study in Mathematics, University of Cambridge 2003.

PhD in Theoretical Physics, Imperial College London 2006.


Petros Wallden is Lecturer in the School of Informatics at the University of Edinburgh, member of the Laboratory for Foundations of Computer Science (LFCS), of the Security and Privacy Group and the Quantum Informatics Group. He is also member of the organising team of the Quantum Information Scotland Network (QUISCO). Dr. Wallden obtained a Masters Degree in Mathematics from University of Cambridge and his PhD in Physics form Imperial College. Since then he held a number of postdoctoral positions (Raman Research Institute, University of Athens, Heriot-Watt University) before joining Informatics, Edinburgh as a Research Associate in 2014 and as a Lecturer in 2018. 

His principal research interests are in the fields of Quantum Cyber Security, Quantum Computation and Quantum Information Theory.
