Dr Ittoop Puthoor

Lecturer

Background

Ittoop is a Lecturer in the School of Computing at Newcastle University. He has a strong interdisciplinary research background in Computer Science and Physics. His interests is to develop and evaluate new quantum technologies for computing and communications. In particular, he is interested in the interplay between Physics and Computer Science, to develop new theories and tools for analysing and guaranteeing the security of quantum cryptosystems. 


Ittoop is associated with the AMBER group (Advanced Model-based Engineering). He was previously involved with the UK Quantum Technology hub for Quantum Communications, where he worked as a senior research associate. He worked in multidisciplinary projects concerning quantum cryptography, quantum information, quantum computing and measurements. This involved collaborations with various academic institutions across UK and also industries like Toshiba Cambridge and BT.


Ittoop received the prestigious Lord Kelvin Adam Smith Scholarship to do his PhD in Computing Science at the University of Glasgow. Ittoop worked with the School of Computing Science and the School of Physics and Astronomy for his interdisciplinary PhD research. His thesis titled “Theory and applications of quantum process calculus” was selected for presentation at the EDAA/ACM SIGDA PhD Forum of the Design, Automation and Test in Europe conference (DATE 2015), which is an international conference and exhibition for electronic system design, and test. Moreover, he has an MTech (Masters of Technology) in Applied Optics at the Indian Institute of Technology (IIT) Delhi and a MSc in Physics from Madras Christian College, Chennai.

Research

My research interests are in three key areas: quantum cryptography, quantum formal methods, and quantum measurements, focussing on fundamental questions to applications in quantum information processing and quantum communications. I am particularly interested in the development of quantum crypto protocols like quantum digital signatures (QDS). QDS provide information-theoretic security which cannot be broken even if a computer has unlimited computing power.


Other area of my research interest is to develop tools from formal methods, for modelling and verifying the correctness of more complex quantum technologies. Since quantum information processing systems has the potential to be more practical and widely used in future, formal methods will play a major role in the design and engineering of of these systems just as they are essential for “classical” systems.


PhD Opportunity: Currently, I am recruiting a PhD student to start in September 2024. If you are interested in applying to do a PhD in one of my research areas, please contact me.
