Quantum computing may still be years away from breaking cryptography, but powerful quantum computers are rapidly advancing, and their impact on cybersecurity is already unfolding. Unlike previous technological shifts, it has the potential to render some of today’s most trusted cryptographic protections obsolete - forcing organizations to rethink how they secure data long before the threat materializes. This moment, commonly referred to as Quantum Day, represents the point at which a quantum computer can effectively compromise today’s unbreakable algorithms. In a PaymentsJournal Podcast, Antoine Kelman , NORAM Payment Services Chief Technology Officer at IDEMIA Secure Transactions, and Tracy Goldberg , Director of Cybersecurity at Javelin Strategy & Research, discussed how organizations should prepare for this eventuality. Getting an Early Start A few years ago, Quantum Day was estimated to occur sometime between 2030 and 2040. However, rapid progress - particularly in countries like Korea - suggests that this timeline may be compressing. Many regulators are now urging organizations to be fully prepared by 2030, which is only a few years away. Preparations are already underway.
