Module mpi_distributed_simulation 

MPI-based Distributed Quantum Simulation

This module provides Message Passing Interface (MPI) support for distributed quantum simulation across multiple compute nodes. It enables simulation of extremely large quantum systems (50+ qubits) by distributing the quantum state across multiple nodes and coordinating quantum operations through MPI.

Features

• MPI communicator abstraction for quantum simulation
• Distributed quantum state management with automatic partitioning
• Collective operations optimized for quantum state vectors
• Support for both simulated MPI (testing) and real MPI backends
• Integration with SciRS2 parallel operations
