Hub PhD opportunity!

The School of Computing at the University of Kent are currently inviting applications for a PhD scholarship in relation to the project ‘Quantum Random Number Generators (QRNGs)’, as part of the EPSRC Quantum Communications Hub. This project will investigate QRNGs, analyse and develop new statistical tests of randomness leading to new certification schemes that would help in guaranteeing the “quantumness” and security of new QRNGs.

PhD project:

The project comprises the study of randomness generation and assessment, with a focus on Quantum Random Number Generators. They will learn how different models generate entropy and how to measure it, as well as how to mount side channel attacks and defend against them. These will include power attacks, temperature-based attacks, voltage attacks, fault injection and others, and will study how to best detect them and protect against them. There will be room as well to study and develop new security quantum protocols that could prove the advantages of using quantum technologies over classical ones. We also aim to study mount general attacks against classical TRNGs that QRNGs are safe from, thus trying to prove a quantum advantage in QRNGs over classical, cheaper and better studied TRNGs. Finally, the candidate will critically examine current certification pathways and suggest new ways to make QRNG certification more stringent and meaningful.

Role requirements The ideal candidate will have a strong background in mathematics and/or physics with an interest in Quantum Physics, and should be interested in testing existing randomness tests, developing new ones, and evaluating the security of both classical random number generators and QRNGs both by analysis of output and by exploring and defending against side-channel attacks. Interest or experience in electronics will be valuable as well.

The candidate will be supervised by Prof. Julio Hernandez-Castro ( and Dr Carlos Perez Delgado (, both core members of iCSS.

Funding availability: Home fee rate of £4,596 per annum together with a maintenance grant of £16,062 which will increase per year in line with UKRI stipend and allowance rates. There will be an option for a 6 month extension depending on available funding.

Length of award: 3 years

Start date: October 2022 or as soon as possible afterwards

Criteria: A first or 2.1 degree or a master’s degree in computer science, mathematics, physics or statistics

All applicants are considered on an individual basis and additional qualifications, professional qualifications and relevant experience may also be taken into account when considering applications. 

Open to UK, EU and Overseas applicants. Please note that funding is available at the home fee rate only – EU and Overseas applicants can apply but will need to make up for the difference between the home fees and overseas fees. We particularly welcome applications from people with disabilities and from Black, Asian and Minority Ethnic (BAME) applicants.
