Sovereign Quantum & Cyber Infrastructure, Riyadh, Saudi Arabia

Cyber defense engineered for the quantum era.

Cryptographically-relevant quantum computers will eventually break the public-key encryption that today’s most sensitive data depends on. SIMAQ designs and deploys the quantum-safe communication infrastructure, fibre and satellite Quantum Key Distribution, optical ground stations, and post-quantum cryptography, that lets Saudi Arabia’s governments, enterprises and national networks get ahead of that threat.

Why quantum-safe, why now

“Harvest now, decrypt later” is already a live threat model.

Adversaries can record encrypted traffic today and decrypt it once a sufficiently powerful quantum computer exists. For data that must stay confidential for years or decades, that risk exists now. NIST finalized the first three federal post-quantum cryptography standards in August 2024, and national cybersecurity authorities worldwide are moving migration planning onto near-term roadmaps.

Threat

Store-now, decrypt-later

Encrypted data intercepted today can be decrypted retroactively once large-scale quantum computers mature.

Standards

NIST FIPS 203 / 204 / 205

ML-KEM, ML-DSA and SLH-DSA are now the U.S. federal standards for quantum-resistant cryptography.

Response

Defense in depth

QKD delivers information-theoretically secure key exchange; PQC hardens classical systems at scale. SIMAQ deploys both.

What we build

Integrated quantum-safe infrastructure, end to end.

From satellite-enabled key distribution to ground-side hardware and enterprise PQC migration, SIMAQ’s stack is designed as one coherent system rather than isolated point products.

QKD via Fibre

Metro and long-haul quantum key distribution over dedicated or dark fibre, engineered for coexistence with live classical traffic.

🛰

QKD via Satellite

Free-space quantum key exchange for distances and geographies fibre cannot reach.

Optical Ground Station

High-precision tracking and optical receiver infrastructure linking satellite payloads to terrestrial networks.

SIMAQ Transmitter

Purpose-built free-space optical transmitter hardware for secure line-of-sight quantum and classical links.

Quantum Sensing

Quantum-enhanced sensing for precision timing, navigation and infrastructure monitoring applications.

🔐

Post-Quantum Cryptography

Migration planning and integration of NIST-standardized lattice- and hash-based algorithms.

Who we are

Building sovereign capability, not dependency.

SIMAQ is a technology-driven organization delivering quantum-safe communication systems and cybersecurity infrastructure for governments, enterprises and national digital ecosystems in Saudi Arabia.
