Quantum computers need vastly fewer resources than thought to break vital encryption
Q Day just got cheaper. New quantum advances mean encryption breakage requires vastly fewer resources than the industry thought—and your infrastructure isn't ready.
Why it matters
Quantum computing's path to breaking current encryption standards is accelerating faster than defensive measures. This shifts the timeline and urgency for enterprise cryptographic migration—a critical board-level risk for any company handling sensitive data.
