Quantum Information (QI)


 Damian Markham - Building 25, 1st Floor, Corridor 25-26, room 112.

Short Presentation

The QI team works on various aspects of quantum information, quantum communication and quantum computation, from foundations to implementations.

This includes the development of cryptographic protocols including quantum key distribution, quantum coin flipping, blind quantum computation, verified quantum computation, secret sharing, and secure multiparty quantum computation.
We also try to understand the fundamental quantum features which give rise to quantum advantages, and how through information perspectives we can understand better the foundations of quantum mechanics.

We address:

  • Practical systems for quantum cryptography and communication complexity (continuous-variable QKD, quantum money, etc), silicon photonics implementations
  • Secure quantum network protocols (secret sharing, blind computing, secure multiparty computation, verification methods), development of multiparty resources
  • Foundations of quantum mechanics and implications to quantum information (toy models, contextuality, steering)

Research activities


The quantum information team is involved in several national and international projects, and sits on several editorial boards, including the steering committee for the GdR "Quantum Engineering, form Fundamental Aspects to Applications (IQFA)", and QCrypt.

We believe strongly in building and supporting a strong local community and are co-founders and hold vice directorship of the Paris Center for Quantum Computing (PCQC.fr).
