Device-independent quantum cryptography


Abstract : The rapid development of applications in quantum information science is paving the way for a new quantum revolution that will guarantee communication security and yield unprecedented computing power. However, it also sets unique and extraordinary challenges regarding the verification and certification that these new quantum devices and protocols operate according to specification. In particular, the security of quantum cryptosystems relies in an essential way on physical assumptions about the functioning of quantum devices, assumptions which may not be met in practical implementations as several successful attacks on commercial and research quantum cryptosystems have demonstrated. We develop in our research group quantum cryptography solutions, such as private random number generation or key distribution, in the device-independent framework, where security can be established based on minimal assumptions about the devices, see e.g. https://arxiv.org/abs/0911.3427 or https://arxiv.org/abs/1612.06828. Candidates interested in doing a PhD along these research lines should have a physics or computer-science background and basic knowledge of quantum information. The projects will be theoretical (but collaboration with experimental group may be possible) and may involve programming in Matlab or other scientific languages.
