Module decision_diagram 

Decision diagram based quantum circuit simulator.

This module implements quantum circuit simulation using decision diagrams (DDs) including Quantum Decision Diagrams (QDDs) and Binary Decision Diagrams (BDDs). Decision diagrams can provide exponential compression for certain quantum states and enable efficient simulation of specific circuit types.
