Virtual Quantum Gates Obscure Proprietary Circuit Information
Summary
USPTO published patent application US20260111773A1 on April 23, 2026, filed October 17, 2024 under Application No. 18919322. Inventors Derek Wang, Ali Javadiabhari, and Alireza Seif Tabrizi disclose methods and systems for obscuring proprietary information encoded in quantum circuits using virtual quantum gates that are not executed on quantum hardware, protecting against power side-channel attacks. The invention transforms target quantum circuits into power-attack resistant forms by encoding proprietary information—including circuit structures, measurement outcomes, initial product states, and parameters—in virtual gates tracked classically and requiring no power.
“The target quantum circuit is transformed into a power-attack resistant quantum circuit by encoding the proprietary information in virtual quantum gates which are not executed on quantum hardware whose logical effects are tracked classically.”
About this source
USPTO classification G06N covers computer systems based on specific computational models: neural networks, knowledge representation, fuzzy logic, expert systems, evolutionary algorithms. With the AI patent boom, this is one of the most-filed application classes in the office. Every newly published application in G06N lands in this feed, around 230 a month. Patent applications publish 18 months after filing, so this feed reveals what AI labs and companies were working on in the prior year and a half. Watch this if you compete in machine learning, file freedom-to-operate analyses, scout acquisition targets in AI infrastructure, or track which research groups are converting publications to patents. GovPing pulls each application with the filing number, title, applicant, and abstract.
What changed
USPTO published patent application US20260111773A1 disclosing a method, system, and computer program product for obscuring proprietary information in quantum circuits using virtual quantum gates. The target quantum circuit and identification of proprietary information to be obscured are received, then the circuit is transformed into a power-attack resistant form by encoding the proprietary information in virtual quantum gates that are not executed on quantum hardware, whose logical effects are tracked classically. Such virtual gates require no power, preventing proprietary information from being detected via power side-channel attacks.
Patent applicants and quantum computing technology developers may review this application for prior art and competitive intelligence. The disclosed method applies to protecting circuit structures, measurement outcomes, initial product states of qubits, and parameters bound in target quantum circuits. Companies developing quantum computing applications involving sensitive algorithms or proprietary circuit designs should consider the virtual-gate encoding approach disclosed herein when assessing IP protection strategies.

OBSCURING PROPRIETARY INFORMATION IN QUANTUM CIRCUITS USING VIRTUAL QUANTUM GATES

Abstract
A method, system, and computer program product for obscuring proprietary information encoded in quantum circuits. The target quantum circuit and the identification of the proprietary information of the target quantum circuit to be obscured are received. Examples of proprietary information include, but are not limited to, a circuit structure, a measurement outcome, an initial product state of qubits, and parameters to be bound in the target quantum circuit. The target quantum circuit is transformed into a power-attack resistant quantum circuit by encoding the proprietary information in virtual quantum gates which are not executed on quantum hardware whose logical effects are tracked classically. Such virtual quantum gates require no power. As a result, proprietary information encoded in the virtual quantum gates cannot be detected via a power side-channel attack. In this manner, proprietary information encoded in quantum circuits is prevented from being stolen by power side-channel attacks.
