siliconindia | | DECEMBER 20258 In the quiet chambers of global finance, a takeover is underway driven not by crashes or reforms, but by quantum time itself. Banks are pouring billions into re-locking their digital vaults, rewriting the code beneath every transaction and identity.This is not caution, it is survival. With attackers already banking encrypted secrets for future unraveling, the race is on to outpace a machine that could unmake trust in minutes. Tomorrow's money is being defended today.Sunil Gupta, Co-founder & CEO, QNu Labs says, "Quantum computers are no longer a distant threat but an imminent reality and once they mature, they will break today's classical encryption in seconds, leaving no data, whether at rest or in motion, safe".How Quantum Is Rewriting Banking's FateThe urgency facing banks today is born from a dangerous imbalance between past security and future power. The encryption systems that protect financial life built on puzzles like prime factorization and complex number problems were designed for machines that think step by step.Quantum computers think in waves. Using qubits that exist in many states at once, they collapse problems that once took centuries into hours. A single breakthrough could expose hidden transactions, aging account records, and financial histories once believed untouchable. And this isn't fear-mongering. Intelligence communities already warn that encrypted data is being quietly collected, stored, and prepared for future quantum decoding. For banks, one successful quantum breach could mean frozen markets, shattered confidence, and regulatory chaos. That is why institutions are rebuilding security from the inside outadopting post-quantum systems, redesigning infrastructure, and retraining people. This is not an upgrade cycle. It is a survival rewrite, where delaying today could damage trust forever.EDITORIAL EXCLUSIVEWHY BANKS ARE SPENDING BILLIONS ON QUANTUM-SAFE ENCRYPTIONUNVEILING THE DUAL REALITIES OF DARK WEBSITES IN THE DIGITAL AGE· Quantum computers can break today's encryption, putting bank data and transactions at risk.· Banks are adopting quantum-safe cryptography and agile systems to secure core operations.· Compliance mandates and operational risks are driving billions in security upgrades.By M R Yuvatha, Senior Correspondent, siliconindia
