Signals from the quantum-safe security landscape.
Curated analysis on the standards, research and deployments shaping quantum-safe communication, with SIMAQ’s perspective on what they mean for Saudi Arabia. Sources are linked in every post.
SIMAQ delivers PQC and QKD workshop for stc group’s Quantum Readiness initiative
SIMAQ ran a workshop on post-quantum cryptography and quantum key distribution as part of stc group’s Quantum Readiness initiative, combining technical sessions with hands-on exercises on the SIMAQ quantum communications simulator. It covered the NIST FIPS 203, 204 and 205 algorithms and QKD operation over fibre, including key exchange, error rate measurement and key management.
KACST and Pasqal launch quantum-safe cryptography research program in Saudi Arabia
KACST’s National Center for Quantum Technologies signed a multi-year research agreement with Pasqal, prioritizing quantum-safe cryptography as the initial focus to protect government networks, critical infrastructure and financial institutions. The agreement, announced at King Salman Science Oasis in Riyadh, aims to develop and eventually bring quantum-safe cryptographic solutions to the Saudi market.
1.6 Tb/s quantum-safe encryption goes live on commercial fibre
Quantum Corridor, Ciena and Toshiba combined NIST-standardized post-quantum cryptography with Toshiba’s QKD platform on Ciena’s WaveLogic 6 Extreme optics, completing the first live commercial deployment to run PQC and QKD together at 1.6 Tb/s on a production fibre network between Chicago and Hammond, Indiana, without replacing existing optical hardware.
US federal buyers get direct GSA access to a PQC platform
QuSecure’s QuProtect post-quantum cryptography and crypto-agility platform was added to Carahsoft’s GSA Schedule contract, giving US federal teams a direct procurement path as agencies work toward NIST’s 2030 key-establishment and 2031 digital-signature migration deadlines.
AI-assisted cryptanalysis breaks a PQC signature candidate before deployment
An Anthropic AI model found a lattice weakness in the HAWK signature scheme within 60 hours, prompting its authors to withdraw it from NIST’s standardization process; NIST’s finalized ML-KEM, ML-DSA and SLH-DSA standards are unaffected.
US executive order sets binding federal PQC deadlines
Executive Order 14412 requires U.S. federal high-value systems to migrate key establishment to post-quantum cryptography by 2030 and digital signatures by 2031, extending equivalent expectations to federal contractors.
NIST finalizes the first three PQC standards
FIPS 203, 204 and 205 are now the U.S. federal baseline for post-quantum cryptography, closing an eight-year evaluation process.
Toshiba takes QKD onto live commercial fibre
Multiplexed QKD running alongside ordinary data traffic on commercial metro fibre is the deployment pattern that matters for national-scale rollout.
Twin-field QKD passes the 800 km mark
A peer-reviewed demonstration secured quantum keys across 833.8 km of ultra-low-loss fibre without trusted intermediate nodes.
Europe’s telcos begin live QKD trials
Telsy, QTI and Portugal’s MEO ran a QKD trial across terrestrial and submarine fibre in the Lisbon metro area.
PQC moves into silicon
The first NIST-compliance-ready PQC test chips signal post-quantum algorithms becoming a baseline hardware requirement.
Quantum sensing leaves the lab
A portable quantum gravity gradiometer detected a buried utility tunnel invisible to conventional survey methods.
