About EigenQ

EigenQ sells PQC+™, which brings trust capabilities from entropy to identity to execution together in a hardware-anchored architecture. EigenQ is designed to establish trust at the foundational layers of computing.[2]

Quantum computing and AI are changing the requirements for security, trust and communications. Organizations need to prepare for that transition without abandoning the technology, infrastructure and trusted relationships they depend on today. From January 1, 2027, new National Security System acquisitions must support CNSA 2.0.[2]

PQC+™ is added to the servers customers already run, in PCIe or M.2. Hybrid post-quantum cryptography, quantum entropy, hardware-rooted trust and crypto agility are built into the servers and systems customers already run. Hardware-rooted identity and attestation confirm a device before it joins. ML-KEM and ML-DSA are NIST post-quantum algorithms. Quantum entropy provides stronger keys, and crypto agility allows algorithms to be updated.[1]

PQC+™ is offered as a drop-in for HPE ProLiant and other servers, bought through the channels customers already use. EigenQ states that its post-quantum algorithms and quantum-entropy DRBG hold NIST Cryptographic Algorithm Validation Program certificates. Federal, state and local procurement is available through GSA and SLED contract paths, alongside the reseller and integrator ecosystem.

CNSA 2.0-aligned, hardware-rooted protection is offered for systems already in service, through the contract vehicles customers use. Hardware-backed keys, trusted identity and crypto agility are offered to protect transactions and customer data.

EigenQ brings together quantum research, cryptography, mathematics, algorithms, hardware and systems engineering. EigenQ combines technology development with an ecosystem-driven path to deployment. EigenQ starts with deployable quantum-ready security and trusted infrastructure today, while building toward broader capabilities across quantum communications, networking and computing.[1][2]
