Module noise_characterization 

Noise Characterization and Mitigation Protocols

This module provides advanced noise characterization techniques and error mitigation strategies for near-term quantum devices (NISQ era).

Characterization Techniques

• Randomized Benchmarking (RB): Characterizes average gate fidelity
• Gate Set Tomography (GST): Full characterization of gate set errors
• Quantum Process Tomography (QPT): Complete process matrix reconstruction
• Cross-Entropy Benchmarking (XEB): Validates quantum advantage

Mitigation Strategies

• Zero-Noise Extrapolation (ZNE): Extrapolates to zero-noise limit
• Probabilistic Error Cancellation (PEC): Inverts noise channels
• Clifford Data Regression (CDR): Calibrates using Clifford circuits
• Dynamical Decoupling: Suppresses decoherence during idle times
