Quantum X Labs Files U.S. Patent Application for Quantum Authentication Security Technology

Patent submission by its QuantumQ Security operation seeks to protect ownership of proprietary quantum technology against unauthorized copying and redistribution

TEL AVIV, Israel, Sept. 24, 2026 (GLOBE NEWSWIRE) -- Quantum X Labs Ltd. (“Quantum X Labs” or the “Company”), a quantum technology company developing technologies across quantum computing, quantum security, quantum software and quantum sensing, today announced that its quantum security operation, QuantumQ Security, has submitted an U.S. patent application with the United States Patent and Trademark Office, titled “Watermarking of Quantum Circuits Using Decomposition of Weyl (KAK) Coordinates in Two-Qubit Blocks.”

This is another quantum cyber milestone and announcement following the appointment of former Mossad chief Yossi Cohen as the President of the Company’s Scientific Advisory Board who, among other duties, will contribute to the expansion of QXL into defense and security markets.

The patent submission relates to a security approach designed to address an emerging challenge in the commercialization of quantum computing: protecting the ownership and intellectual property of quantum circuits against unauthorized copying, redistribution and use. As quantum computing advances toward broader commercial deployment, proprietary quantum algorithms and circuits may represent increasingly valuable intellectual property. Quantum circuits are optimized and decomposed into elementary gates before being executed on quantum hardware, including through third-party or cloud-based quantum computing environments. This process may create potential exposure of proprietary quantum designs to unauthorized access, copying or redistribution.

QuantumQ Security’s patent submission seeks to establish a method for embedding identifiable ownership information within quantum technology through the decomposition of Weyl, or KAK, coordinates in two-qubit blocks. The objective is to enable an owner to subsequently verify ownership while seeking to limit the computational overhead and fidelity degradation that can arise from certain existing watermarking techniques.

Watermarking in this context refers to modifying a quantum computation in a controlled manner so that an embedded signature can be associated with an authorized owner. Unlike conventional digital watermarking, quantum watermarking must operate within the unique constraints of quantum computation, where additional gates and increased circuit depth can introduce additional noise and potentially reduce execution fidelity.

This challenge is particularly relevant to Noisy Intermediate-Scale Quantum (“NISQ”) systems, where quantum resources remain constrained and qubits are susceptible to errors. Security mechanisms intended for these systems therefore need to consider not only their ability to establish ownership, but also their potential effect on circuit depth, two-qubit gate counts and overall performance. The Company believes that the ability to establish and verify ownership of proprietary quantum technology could become increasingly important as quantum computing evolves toward cloud-based and distributed models in which developers may execute proprietary algorithms on quantum infrastructure controlled by third parties.

The patent submission forms part of QuantumQ Security’s broader strategy of developing security technologies specifically for the emerging quantum computing ecosystem. Rather than focusing solely on adapting classical cybersecurity methods to address quantum-related threats, QuantumQ Security is developing technologies intended to use the properties and architecture of quantum systems themselves as part of the security framework.

“As quantum computing becomes increasingly commercialized, proprietary quantum algorithms and the circuits implementing them could become highly valuable intellectual property,” said Prof. Nir Sharon, Chief Technology Scientist of Quantum X Labs. “A developer may eventually need to send proprietary quantum technology to computing infrastructure that it does not own or control. Our work is focused on creating a mechanism through which ownership can effectively travel with that technology, while seeking to minimize the computational burden associated with that protection.”

The patent submission represents another component of QuantumQ Security’s developing multi-layer quantum security architecture, which is focused on detection, protection and verification across the quantum computing lifecycle.

Quantum X Labs intends to continue the theoretical evaluation, simulation and testing of the watermarking technology as part of its development process.
