Test method validation using quantum algorithms

A quantum computing device, comprising:

• a memory;
• a processor device coupled to the memory, the processor device to:
• initiate a first quantum algorithm comprising a test method implemented as a quantum oracle, wherein the first quantum algorithm receives an input of a first quantum register comprising a plurality of qubits and a second quantum register comprising one qubit, each qubit of the plurality of qubits in the first quantum register corresponding to a respective test case of a corresponding plurality of test cases for the test method;
• receive an output of the first quantum algorithm comprising the first quantum register, wherein each of the plurality of qubits in the first quantum register comprises a resulting quantum state based on the first quantum algorithm;
• initiate a second quantum algorithm, wherein the second quantum algorithm receives an input of a third quantum register and the output of the first quantum algorithm;
• perform, based on the second quantum algorithm, a measurement on the first quantum register and a measurement on the third quantum register, wherein the measurement on the first quantum register and the measurement on the third quantum register are indicative of a pass or fail of each of the corresponding plurality of test cases;
• and
• determine, based on the measurement on the first quantum register and the measurement on the third quantum register, that the test method passed or failed.

A non-transitory computer-readable storage medium that includes computer-executable instructions that, when executed, cause one or more processor devices to:

• initiate a first quantum algorithm comprising a test method implemented as a quantum oracle, wherein the first quantum algorithm receives an input of a first quantum register comprising a plurality of qubits and a second quantum register comprising one qubit, each qubit of the plurality of qubits in the first quantum register corresponding to a respective test case of a corresponding plurality of test cases for the test method;
• receive an output of the first quantum algorithm comprising the first quantum register, wherein each of the plurality of qubits in the first quantum register comprises a resulting quantum state based on the first quantum algorithm;
• initiate a second quantum algorithm, wherein the second quantum algorithm receives an input of a third quantum register and the output of the first quantum algorithm;
• perform, based on the second quantum algorithm, a measurement on the first quantum register and a measurement on the third quantum register, wherein the measurement on the first quantum register and the measurement on the third quantum register are indicative of a pass or fail of each of the corresponding plurality of test cases;
• and
• determine, based on the measurement on the first quantum register and the measurement on the third quantum register, that the test method passed or failed.
