Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current quantum Software Development Kits (SDKs) lack thorough testing, leading to potential crashes and vulnerabilities due to untested quantum programs, which can result in system failures and security loopholes.
Innovation Solution
An automated fuzzy-based end-to-end testing tool that receives and transforms QASM programs with mutating inputs to test the robustness and reliability of quantum SDKs, simulating crashes to identify and address potential issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If quantum SDKs are released without thorough testing, then development speed is improved, but system reliability deteriorates
Solution Approach 1:
The patent implements preliminary action by automatically generating test cases and executing fuzz testing before the quantum SDK is released. The testing tool transforms QASM programs into transformed QASM programs and executes them against the SDK to identify potential crashes and vulnerabilities in advance, ensuring reliability issues are caught before deployment.
Solution Approach 2:
The patent applies self-service by creating an automated testing system that independently generates test inputs, transforms quantum programs, executes tests against the SDK, and reports results without requiring manual intervention. The system uses genetic algorithms to automatically evolve test cases and identify edge cases that might cause crashes.
2Reliability
If comprehensive testing is performed on quantum SDKs, then system reliability is improved, but testing complexity increases
Solution Approach 1:
The patent uses copying by creating transformed copies of original QASM programs. The transformation process generates variant versions of quantum programs that preserve the original logic while introducing variations that can expose edge cases and vulnerabilities. These transformed programs serve as test inputs that comprehensively stress-test the SDK without requiring entirely new test case designs.
Solution Approach 2:
The patent applies parameter changes by systematically varying parameters in the transformed QASM programs, such as changing quantum gate parameters, qubit indices, and circuit depths. The genetic algorithm evolves these parameters to generate diverse test cases that cover different execution paths and potential failure modes in the quantum SDK.
3Difficulty of detecting and measuring
If fuzz testing with mutated inputs is used, then bug detection capability is improved, but computational resources increase
Solution Approach 1:
The patent implements partial or excessive action by generating a large number of transformed test cases that exceed minimal testing requirements. The system deliberately creates more test inputs than strictly necessary, using genetic algorithms to evolve populations of test cases that thoroughly explore the input space, accepting the computational cost as necessary for comprehensive bug detection.
Solution Approach 2:
The patent uses feedback by monitoring the results of each fuzz testing iteration and using this information to guide subsequent test case generation. The genetic algorithm receives feedback from executed tests about which transformed programs caused crashes or errors, and uses this feedback to evolve better test cases that are more likely to expose vulnerabilities in subsequent iterations.

AI summary
The subject disclosure relates generally to an automated testing tool for quantum software development kits (SDKs). A system in accordance with an embodiment comprises a memory that stores computer-executable components. A processor is operably coupled to the memory and executes the computer-executable components stored in the memory. The computer-executed components comprises: a transformation component that receives a qasm program and transforms the qasm program; a testing component that tests the transformed qasm program on the SDK; and a reporting component that reports whether a quantum SDK has functioned properly or failed for the transformed qasm program.
