Quantum Banknotes and Information-Theoretic Credit Cards – quBIC

Submission summary

For a quantum-safe future, classical security systems as well as quantum protocols that guarantee security against all adversaries must be deployed. Here, we will study and implement one of the most promising quantum applications, namely unforgeable quantum money. A money scheme enables a secure transaction between a client, a vendor and a bank via the use of a credit card or via the use of banknotes, with maximal security guarantees. Our objectives are to perform a theoretical analysis of quantum money schemes, in realistic conditions and for encodings in both discrete and continuous variables, and to demonstrate experimentally these protocols using state-of-the-art quantum memories and integrated detection devices. The technologies we will develop are also useful for future quantum network applications. Our multidisciplinary experience, the recent breakthroughs in quantum technologies, and our comprehensive methodology are a guarantee to the successful completion of the project.
