JOHNSTOWN, PA – May 19, 2026 – In a move to defend the nation’s most vital systems against a new era of cyber warfare, Concurrent Technologies Corporation (CTC) has announced a strategic partnership with Quantum Knight Inc. The collaboration aims to accelerate the deployment of post-quantum cryptography (PQC) to shield U.S. government, defense, and critical infrastructure networks from adversaries armed with future quantum computers.
The partnership brings together CTC, a nonprofit applied scientific research organization with deep roots in government and defense projects, and Quantum Knight, a developer of advanced, software-based PQC solutions. The alliance will focus on integrating and deploying Quantum Knight’s CLEAR™ cryptosystem, a platform designed to secure sensitive data against threats that could render much of today’s encryption obsolete.
“Post-quantum cybersecurity is no longer theoretical. Adversaries are already targeting infrastructure that was never designed for modern cyber warfare,” said Edward J. Sheehan Jr., President and CEO of CTC, in a statement announcing the partnership. “Our role as a non-profit is to identify and deliver technologies that are ready for real-world deployment, and this partnership reflects that mission.”
The Looming Quantum Threat
The urgency behind this initiative stems from a widely anticipated technological shift known as “Q-Day”—the moment a sufficiently powerful quantum computer becomes capable of breaking the public-key encryption that underpins global digital security. While estimates for Q-Day vary, many experts place it in the early 2030s, and the threat is already materializing through “harvest now, decrypt later” (HNDL) attacks. In these scenarios, adversaries are siphoning and storing vast amounts of encrypted data today, betting they can unlock it once quantum computing matures.
This puts long-term sensitive information—from national security secrets and financial…
