 ## Overview
 This module provides various tools and utilities for simulating quantum systems. It includes functions for handling common quantum operations, such as Pauli operators, outer products, commutators, and anti-commutators. Additionally, it provides a class `qsimulations` to manage and simulate time-dependent quantum systems with ancillary qubits and damping operators.
