HSBC has successfully trialled quantum-secure technology for buying and selling tokenized physical gold, marking a significant advancement in protecting against potential quantum computing attacks. The bank first introduced tokenized physical gold to institutional investors last year and has now extended this offering to retail clients in Hong Kong via its HSBC Gold Token. In collaboration with Quantinuum, HSBC employed post-quantum cryptography to enhance the security and interoperability of its digital gold tokens across distributed ledgers and digital wallets. This technology aims to safeguard sensitive data from 'store now, decrypt-later' cyber incidents, where attackers could exploit quantum computing capabilities in the future. Philip Intallura, HSBC's Global Head of Quantum Technologies, emphasized the bank's commitment to pioneering cybersecurity solutions for the evolving digital asset landscape. This initiative reflects HSBC's proactive approach to mitigating risks associated with emerging technologies in finance.
