Abstract: Systems and methods for quantum computing devices are provided. In one example, a method may include preparing one or more qubits in a selected initial state of a set of initial states. The method may include implementing a first quantum circuit for n repetitions on the one or more qubits, the first quantum circuit comprising one or more quantum gates. The method may include implementing a second quantum circuit to map a state of the one or more qubits towards a target state, the second quantum circuit based on a unitary associated with the first quantum circuit. The method may include performing a measurement of the one or more qubits. The method may include determining a fidelity between the first quantum circuit and the unitary based at least in part on the measurement of the one or more qubits.
