Qiskit ZX Transpiler

This tool provides a transpiler pass for Qiskit that leverages ZX-Calculus for quantum circuit optimization. Implemented using the PyZX library, it offers an alternative method to reduce circuit complexity.

Key features include:

• Integration as a standard Qiskit transpiler pass.
• Utilization of ZX-Calculus methods for optimization.
• Built upon the PyZX library.
• Supports custom optimization functions.
• Exposed as a pass manager stage plugin (optimization_method="zxpass").

This pass aims to improve circuit characteristics such as depth and gate count by applying ZX-diagram simplification techniques.
