- Microsoft accelerates its quantum-safe roadmap, targeting 2029 for migrating key services to post-quantum cryptography (PQC).
- New research demonstrates quantum attacks are feasible with far fewer resources, heightening the “harvest now, decrypt later” threat.
- Major tech firms like Google and Cloudflare have publicly committed to similar 2029 deadlines for securing their infrastructures.
- The U.S. government has issued executive orders with hard deadlines for federal agencies to adopt PQC for critical systems.
On July 1, 2026, Microsoft announced it is drastically accelerating its quantum-safe security plans, as reported by the company’s chief technology officer. The tech giant now believes cryptographically relevant quantum computers could arrive sooner than expected, making immediate preparation essential.
Consequently, Microsoft is speeding up its Quantum Safe Program timeline to transition critical products to post-quantum cryptography by 2029. The company is also embedding PQC requirements into its broader Secure Future Initiative.
Key focus areas include upgrading network cryptography and building crypto-agility into stored data systems. “This brings quantum-safe readiness into the same disciplined engineering framework we use for other critical security outcomes,” said Mark Russinovich.
Microsoft emphasized that crypto-agility is essential, requiring systems to read legacy data while writing with new algorithms. The company explained this requires self-describing cryptographic metadata or versioned ciphertext formats.
This development follows a recent executive order from U.S. President Donald Trump setting hard deadlines for federal agencies. Meanwhile, other major tech companies are moving in lockstep with similar deadlines.
Google announced a program for quantum-safe HTTPS certificates and publicly committed to migrating its infrastructure by 2029. Web infrastructure firm Cloudflare has also followed suit with parallel plans.
The urgency is driven by the “harvest now, decrypt later” threat, where adversaries collect encrypted data to decode later. Meanwhile, recent research breakthroughs suggest quantum attacks are closer than once thought.
A team from Google disclosed a drastically improved quantum algorithm to break elliptic curve cryptography. Separately, academics demonstrated a new error-correction approach that could make Shor’s algorithm practical with far fewer qubits.
