Quantum computing has important implications for the field of cryptography. On the one hand, techniques in quantum information open up new possibilities for secure communication (e.g. quantum key distribution), while on the other hand, achieving security might be harder in a world where attackers potentially possess quantum computers.

The aim of this project is to familiarize students with a variety of topics within quantum cryptography, so that they are able to read and understand research papers in the field. We will study quantum key distribution in more detail, consider hardware limitations, as well as cryptographic primitives such as oblivious transfer, bit commitment and secret sharing in a quantum setting. In particular, we will highlight the differences with the classical setting for these tasks. There will also be time to study recent developments based on the interest of the students.


In the first weeks, students will follow this online course on Quantum Cryptography, and we will meet regularly to work with the material together. Towards the end of the project period, students will individually analyse and present a recent research paper on a topic of their choice.


Basic knowledge of quantum information, as covered in the courses Quantum Computing by Ronald de Wolf or Symmetry and Quantum Information by Michael Walter. In particular Chapters 1,2,10,11,12,13,14 of Ronald de Wolf’s lecture notes, and Chapter 0 of the online course linked above.


homework assignments, presentation, small report.
