//! Quantum device connectors for the QuantRS2 framework.
//!
//! This crate provides connectivity to quantum hardware providers like IBM Quantum,
//! Azure Quantum, and AWS Braket. It enables users to run quantum circuits on real
//! quantum hardware or cloud-based simulators.
//!
//! ## Recent Updates (v0.1.0)
//!
//! - ✅ Re-enabled enhanced SciRS2 modules with full API compliance
//! - ✅ `scirs2_hardware_benchmarks_enhanced`: ML-driven performance prediction and analysis
//! - ✅ `scirs2_noise_characterization_enhanced`: Advanced noise modeling with SciRS2 stats
//! - ✅ Enhanced transpilation using SciRS2 v0.1.2 Stable Release's graph algorithms
//! - ✅ Stable APIs for IBM Quantum, Azure Quantum, and AWS Braket
//! - ✅ All 406 tests passing with zero compilation warnings
//! - ✅ Full SciRS2 Policy compliance for scientific computing operations
