In this work, we present a systematic approach to implementing basic assertions in quantum circuits in order to verify classical states across any number of qubits. Our methodology utilizes fundamental quantum gates available on all gate-based quantum computing platforms. Through strategic combinations of these gates, we construct the ‘Equal to’, ‘Different than’, ‘Greater than’, and ‘Lower than’ comparators. By introducing single-qubit comparators and demonstrating how they can be expanded to handle multiple qubits, we provide a scalable method for verifying classical states in quantum circuits. This work provides the groundwork for robust testing procedures in quantum computing, a critical factor in the continued growth and reliability of this rapidly advancing field.
