A Framework for Secure Financial Transactions with Relativistic Quantum Tokens

Join a Zoom talk on June 4 to explore a cutting-edge framework for secure financial transactions using relativistic quantum tokens.

Research into quantum money dates back to the 1980s, with security rooted in the no-cloning theorem and the inherent uncertainty of quantum measurements. However, practical implementation has long been delayed by the absence of quantum memory. This project bridges the gap by integrating quantum and classical techniques to demonstrate a proof-of-concept transaction system. Combining quantum communication and cryptography, the project combine quantum key distribution, hashing, and GPS-based time synchronization protocols to create a secure quantum banknote framework. This approach enables the anonymous generation, exchange, and verification of quantum banknotes while maintaining robust security against counterfeiting.

Isa Tippens is a Computer Science student at the University of the Western Cape, South Africa, studying towards a MSc degree in Computer Science with a focus in quantum computing.
