The quantum deadline is unclear. The need to prepare isn’t.
For the past decade, quantum computing has been relegated to the horizon, a distant, theoretical challenge rather than an immediate operational imperative.
Breakthroughs have generated headlines, but without a firm deadline for when quantum computers could threaten today’s cryptographic standards, CISOs have had little incentive to make quantum readiness an immediate priority. IBM’s 2025 Quantum-Safe Readiness Index shows how much work remains, with the average organization scoring just 25 out of 100.

Yet, that window of preparation is contracting rapidly. This spring, Google warned that “quantum frontiers may be closer than they appear,” pointing to advances in hardware, error correction, and algorithms that are accelerating progress toward cryptographically-relevant quantum computers. Google has since set a 2029 target for completing its own migration to post-quantum cryptography (PQC).
Yet, that growing urgency still comes without a firm deadline. Unlike the fixed, binary deadline of Y2K from years ago,...
