Before Q-Day: The Race to Quantum First
Two independent research teams have revised downward the estimated resources needed to break widely used public-key encryption using quantum computing, with one finding that Shor's algorithm could run at cryptographically relevant scale with as few as 10,000 neutral-atom qubits. The developments, reported around March 30, 2026, bring the theoretical threshold for breaking current encryption standards meaningfully closer.
Why this matters: The timeline just got shorter. Encryption protects your banking, your messages, and classified government traffic. Quantum computers powerful enough to break it do not exist yet, but the estimates for when they might keep moving in one direction. The threat is real enough that adversaries are already collecting encrypted data now to decrypt later. That strategy has a name: harvest now, decrypt later. Every month that governments and companies delay migrating to post-quantum encryption standards is another month of exposure they are choosing to accept.
