1//! Hardware-specific compiler passes for quantum circuit optimization
2//!
3//! This module provides advanced compiler passes that leverage hardware-specific
4//! information including topology, calibration data, noise models, and backend
5//! capabilities to optimize quantum circuits for specific hardware platforms.
