Google has reignited debate over the future of digital security, revealing that the hardware needed to break widely used encryption could be closer than previously thought.For now, the million-qubit quantum computer remains a goal rather than a reality. However, the pace of progress in the field means the transition to quantum-resistant security measures can no longer be considered a distant concern. The study provides a blueprint for what a future attack might look like and serves as a call to action for the global security community to prepare for a post-quantum world.The hypothetical machine would need to run continuously for five days, maintain extremely low error rates, and coordinate billions of logic operations without interruption.The security implications are significant. RSA and similar cryptographic systems underpin much of the world’s secure communications, from banking to digital signatures. The study’s findings reinforce the urgency of moving to post-quantum cryptography (PQC) – new standards designed to withstand attacks from quantum computers. What is yoour take on Quantum security threat ?
