UZC partnered with Visa to develop "Q-AdSecure"—the world's first quantum-secure advertising transmission protocol utilizing quantum key distribution (QKD) and post-quantum cryptography to redefine brand communication security standards in digital payments. 

The system integrates three core modules: an entanglement-based quantum random number generator producing over 100,000 encryption keys per second, lattice-based cryptography algorithms protecting creative assets against future quantum computer attacks, and a blockchain-powered quantum key management platform enabling automatic key distribution and destruction through smart contracts. 

During APAC digital payment promotions, UZC Singapore Quantum Lab incorporated Eastern ink wash painting aesthetics into qubit encoding protocols, London security team designed anti-eavesdropping channels using topological insulator principles, while Silicon Valley Algorithm Center developed real-time quantum bit error rate monitoring for adaptive encryption adjustment. 

Deployment data showed the system successfully thwarted simulated quantum attacks, reduced ad transmission latency to millisecond levels, and maintained a zero-security-incident record. This initiative significantly elevated Visa's digital payment brand safety scores and received quantum security certification from the Global Cybersecurity Alliance. 

UZC and Visa are now exploring quantum-secure communications expansion into metaverse advertising, developing quantum entanglement-based cross-virtual-world brand message synchronization solutions.
