Grover’s Algorithm vs AES – Why “Ignore It” Is Almost Right
The consensus says Grover will never break AES-128. The math checks out on today's assumptions. But those assumptions are built on surface codes and superconducting hardware, and the ground is already shifting. Scan the quantum computing coverage of Bitcoin and…

Cisco Research Proves That One Post-Quantum Layer Can Protect Payload Confidentiality — But Authentication Requires Migrating Every Layer
A Cisco Research paper proves that one post-quantum layer suffices for payload confidentiality but every layer must migrate for authentication — and that upgrading to WPA3 worsened quantum security.

Harvard’s Cascade Neural Decoder Cuts Quantum Error Rates 17×, Reveals Waterfall Effect
Harvard's Cascade decoder achieves logical error rates 17× below the best existing decoders on quantum LDPC codes and reveals a "waterfall" regime of error suppression that could reduce the physical qubit count required for a CRQC by 40% or more.

PQC Signature Migration Before Encryption: Why Trust Infrastructure Comes First
Most PQC migration guides tell you to protect data first. But recent research confirms that signature algorithms fall faster, and the blast radius of a compromised signing key dwarfs that of a decrypted session. Here's why I'm telling CISOs to…
