PhD scholarship in Quantum Information Security and Randomness Certification – DTU Physics
Kgs. Lyngby, Denmark
Job Description

Are you excited about information security and the novel possibilities opened up by quantum technology? Are you fascinated by quantum physics and intriguing phenomena such as quantum entanglement, nonlocality, and indeterminism in quantum measurements?
At the Section for Quantum Physics and Information Technology, we are seeking an excellent and highly motivated PhD candidate to work on the theory of novel quantum randomness certification protocols. In this project, we will connect fundamental physics to information security, establishing the security analysis of new, cutting-edge devices which can be implemented with quantum optical technology and will be realised in the lab. The theoretical work will be carried out in close collaboration with experimental colleagues and engineers at DTU Physics as well as other academic and industry actors, including the University of Ghent, the Danish National Metrology Institute, and DTU spin-off Alea Quantum Technologies.
The successful candidate will be enrolled in the Section for Quantum Physics and Information Techology (QPIT) of DTU Physics, which hosts a wide range of activities in both fundamental quantum information science and applied quantum technology, including the national Centre of Excellence for Macroscopic Quantum States (bigQ). In particular, the candidate will be part of the theory subgroup headed by Prof. Jonatan Bohr Brask and the quantum cryptography activities headed by Prof. Tobias Gehring.
Responsibilities and qualifications
We are looking for a highly motivated student who will be exploring both the development of new quantum-optical setups for randomness certification and the derivation of rigorous security proofs, quantifying the extractable randomness from real devices. A particular focus will be on devices that need not be fully trusted, providing an extremely high level of security in the so-called device-independent and semi-device-independent regimes.
You will be using tools and techniques from quantum information theory, theoretical quantum optics, and numerical optimisation to:

  • Develop new optical schemes for quantum random-number generation (QRNG) that are readily implementable yet provide strong cryptographic security.
  • Analyse new and existing QRNG protocols in order to provide thorough and reliable security proofs, applicable under realistic operating conditions.
  • Implement efficient methods for online randomness extraction to be used with new, high-speed QRNG devices.

We expect you to have an excellent academic record, to be curious and exited about quantum physics and information technology, and to be collaborative and able to work in a team. Prior experience with quantum information theory and quantum optics is an advantage. Good coding skills, e.g. in Python, and experience with convex optimisation is also an advantage.
Good communication skills in both spoken and written English are a requirement. You are expected to teach and supervise BSc and MSc students.
You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.
Approval and Enrolment 
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education . 
The assessment of applications will be carried out by Professors Jonatan Bohr Brask and Tobias Gehring together with Head of Section and Centre leader Professor Ulrik L. Andersen.
We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.
Salary and appointment terms
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The period of employment is 3 years.
Starting date is as soon as possible (according to mutual agreement). The position is a full-time position.

Further information
Further information may be obtained from Prof. Jonatan Bohr Brask, [email protected] .
You can read more about the QPIT section at DTU Physics at .
If you are applying from abroad, you may find useful information on working in Denmark and at DTU at DTU – Moving to Denmark . Furthermore, you have the option of joining our monthly free seminar “PhD relocation to Denmark and startup “Zoom” seminar ” for all questions regarding the practical matters of moving to Denmark and working as a PhD at DTU. 
Application procedure 
Your complete online application must be submitted no later than 7 June 2024 (23:59 Danish time). Applications must be submitted as one PDF file containing all materials to be given consideration. To apply, please open the link "Apply now", fill out the online application form, and attach all your materials in English in one PDF file. The file must include:

  • A letter motivating the application (cover letter)
  • Curriculum vitae 
  • Grade transcripts and BSc/MSc diploma (in English) including official description of grading scale

You may apply prior to ob­tai­ning your master's degree but cannot begin before having received it. 
Applications received after the deadline will not be considered.
All interested candidates irrespective of age, gender, race, disability, religion or ethnic background are encouraged to apply.
At DTU Physics, we carry out cutting-edge research in modern physics, with particular focus on four main areas: quantum technology, sustainable energy, materials, and biophysics. Our focus is both to acquire greater knowledge about basic scientific problems and to conduct research oriented towards use in societies and companies.
Technology for people
DTU develops technology for people. With our international elite research and study programmes, we are helping to create a better world and to solve the global challenges formulated in the UN’s 17 Sustainable Development Goals. Hans Christian Ørsted founded DTU in 1829 with a clear mission to develop and create value using science and engineering to benefit society. That mission lives on today. DTU has 13,500 students and 6,000 employees. We work in an international atmosphere and have an inclusive, evolving, and informal working environment. DTU has campuses in all parts of Denmark and in Greenland, and we collaborate with the best universities around the world.
