Simulating unknown qubit-unitary inversion with zero-noise extrapolation

In this work, we demonstrated the feasibility of using Zero-Noise Extrapolation (ZNE), an error mitigation technique, in the unknown qubit-unitary inversion protocol based on work by Yoshida S, et al. [Physical Review Letters 131.12 (2023)]. Using noise models and the Mitiq toolkit, we apply ZNE and analyze their deviation from the theoretical results.
