Toronto, Ontario--(Newsfile Corp. - September 29, 2026) - 01 Quantum Inc. (TSXV: ONE) (OTCQB: OONEF) ("01 Quantum" or the "Company") one of the first-to-market, enterprise level cybersecurity providers for the quantum computing era, today announced that the United States Patent and Trademark Office ("USPTO") has issued U.S. Patent No. 12,744,764 B1, titled "Secure AI Operations," covering technology underlying the Company's secure AI solutions.

The patent protects a system and methods designed to enable secure AI operations using computation-preserving cryptography ("CPC"). The patented technology enables sensitive user data to be encrypted before being submitted to an AI model, processed while remaining encrypted, and returned to the user as an encrypted prediction or result. The technology is designed to protect both sensitive user data and proprietary AI models throughout the AI inference process.

The patent also covers applications involving a secure AI model marketplace, where AI model users and AI model vendors can interact while maintaining cryptographic protection over sensitive data and proprietary model intellectual property. This architecture is particularly relevant for organizations operating in data-sensitive environments where conventional AI deployment can create concerns surrounding data privacy, model security and confidentiality.

The issuance follows the Company's May 5, 2026 announcement that the USPTO had issued a Notice of Allowance for the patent application.

01 Quantum's secure AI technology is being developed to address the security and privacy requirements associated with the growing use of AI in sensitive and mission-critical applications. The Company recently announced that it will showcase quantum-safe encrypted AI analytics at GCXpo 2026 hosted by Area X.O and operated by Invest Ottawa, in partnership with government and industry stakeholders, including encrypted-prompt inference for image recognition, secure data sharing and anomaly detection.

The newly issued patent complements 01 Quantum's existing intellectual property portfolio and advances the Company's strategy of developing patent-protected technologies designed to secure data, communications and AI applications for the post-quantum era.

Executive Commentary:

Andrew Cheung, CEO of 01 Quantum, stated, "The issuance of this patent represents an important milestone for 01 Quantum and further strengthens the intellectual property foundation supporting our secure AI strategy. As AI becomes increasingly embedded in mission-critical environments, organizations require the ability to benefit from AI without exposing their most sensitive information or proprietary models. Our technology is designed to enable AI inference while keeping sensitive data encrypted throughout the process."

Mr. Cheung continued, "We believe this capability has significant potential across enterprise, government and defence applications where data sovereignty, confidentiality and security are paramount. With the patent now formally issued, we have further strengthened the protection around technology that is becoming an increasingly important component of our commercialization strategy."
