Field reports from the frontier.
Analysis of quantum computing breakthroughs, security threats, post-quantum cryptography deployment, and the global industry landscape.
IBM Heron R2 Crosses 156 Qubits — What It Means for Cryptographic Timelines
The latest Heron generation pairs higher qubit counts with materially lower two-qubit error rates. We map the impact on Shor's algorithm feasibility windows.
Harvest Now, Decrypt Later: 2026 Field Report
State-level adversaries are actively archiving encrypted traffic. Here is what we are seeing across telco backbones and enterprise VPN flows.
ML-KEM in Production: Five Deployment Pitfalls We Keep Seeing
Kyber/ML-KEM rollouts often look clean on paper and brittle in production. The most common failure modes — and how to avoid them.
Google Willow's Below-Threshold Result: Why Engineers Are Watching Distance-7
Willow demonstrated exponential error suppression with code distance. The engineering implications matter more than the headline.
Updated Shor's Algorithm Resource Estimates, Spring 2026
Tightened Toffoli counts and improved windowed arithmetic shrink the qubit-count requirement for breaking RSA-2048 below the 10-million mark in optimistic models.
Mapping China's 2026 Quantum Investment: USTC, Origin, and the New Hefei Lab
Public funding announcements, paper output, and patent filings paint a clear picture of where Chinese quantum capability is heading.
NIST FIPS 206 (FN-DSA / Falcon): Where the Standard Stands
Falcon's compact signatures come at the cost of implementation complexity. The trade-off is now clearer than it was a year ago.
Trapped-Ion vs Superconducting: The 2026 Engineering Picture
Quantinuum's H2 and IonQ's Forte continue to lead on fidelity. Superconducting devices lead on speed and qubit count. Here is how the trade-offs are evolving.
QKD in 2026: A Reality Check on Real-World Deployment
Quantum Key Distribution is technically impressive and operationally limited. Where it actually fits in a defense-in-depth posture.
Post-Quantum TLS: State of Deployment, April 2026
Hybrid X25519+ML-KEM-768 is now the default for several major CDNs and browsers. The long tail is, as always, the hard part.
