Module concatenated_error_correction 

Concatenated Quantum Error Correction with Hierarchical Decoding

This module implements concatenated quantum error correction codes that provide enhanced error protection through multiple levels of encoding. Concatenated codes work by applying error correction codes recursively: the physical qubits of an outer code are themselves logical qubits encoded using an inner code.

This implementation features:

• Multiple concatenation levels for exponential error reduction
• Hierarchical decoding with error propagation tracking
• Adaptive thresholds based on error rates
• Resource-efficient syndrome processing
• Support for heterogeneous inner and outer codes
