Quantum B
We protect the systems the world depends on with quantum-resistant security built for tomorrow.
From power grids, water and gas networks, and robotic systems, to natively digital identity infrastructures — our technology is engineered for the threat landscape of tomorrow.
About Us
Quantum B has two primary goals: to pioneer quantum-safe cryptography for next-generation cybersecurity and to enable quantum-secure blockchain infrastructure. We believe the world's digital foundations — communications, identity systems, and the networks that run critical services — must be protected against the quantum threat before it arrives.
From power grids and industrial networks to digital identity and blockchain infrastructure, our technology is engineered for the threat landscape of tomorrow.
A practical portfolio of technologies — from key distribution to entropy to migration frameworks — built for real operational environments.
Highest-assurance quantum key distribution for environments that require physics-based key exchange — security grounded in the laws of quantum mechanics, not computational assumptions.
Deployable quantum-resistant key distribution via post-quantum cryptography (Kyber/FIPS-203) and a genuine on-chip QRNG. Works with existing IP infrastructure — no fiber optic links required.
Staged migration framework from classical cryptography to quantum-safe and full quantum-cryptographic architectures — structured, measurable, and designed for operational continuity.
Trusted quantum entropy for cryptographic systems and infrastructure — available as an on-site appliance or API-based service powered by ID Quantique hardware.
NIST-standardised algorithms and structured PQC rollouts — cryptographic visibility, risk prioritisation, and phased integration for today's environments.
Featured Product
pQKD is Quantum B's groundbreaking cybersecurity appliance. It distributes cryptographic keys over a post-quantum-secured out-of-band channel — no fiber optic links required — using Kyber KEM (FIPS-203) and a genuine on-chip QRNG from ID Quantique. A single deployable device that works with existing network infrastructure, today.
Ecosystem
We collaborate with leading hardware manufacturers, technology providers, and research institutions across the quantum security ecosystem.
