We’re excited to welcome Isa Tippens from the University of Western Cape as our featured speaker in this engaging seminar series. The event will be held in a hybrid format, with in-person attendance at Wits, Gatehouse, and online participation available.

Research into quantum money dates back to the 1980s, but its practical implementation has been delayed due to the absence of efficient quantum memory. Isa’s 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 combines 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.
