Circuit Unoptimization

This library provides an implementation of quantum circuit unoptimization, a technique used as an alternative noise-scaling method for Zero-Noise Extrapolation (ZNE). Instead of folding gates, unoptimization deliberately increases the circuit depth and gate count by adding identity operations that do not alter the circuit's logical function. This process amplifies the noise experienced by the circuit, providing the necessary scaling factor for ZNE without relying on traditional circuit folding methods.

Key features:

• Implements the elementary unoptimization recipe.
• Enables comparative benchmarks against other ZNE scaling techniques like folding.
• Offers a different approach to noise amplification for error mitigation.
