1Reliability
If quantum computing devices operate without comprehensive error classification, then device complexity is reduced, but reliability of quantum operations deteriorates
Solution Approach 1:
A classical computing system is introduced as an intermediary between quantum computing devices and error correction mechanisms. The classical system receives quantum error data, determines error types using classification tags, and processes correction requests accordingly. This mediator handles the complexity of error classification externally, allowing quantum devices to maintain operational simplicity while achieving improved reliability through systematic error management.
2Measurement precision
If quantum error data is collected and classified in detail, then measurement precision of error types improves, but loss of time for error processing increases
Solution Approach 1:
The system performs preliminary error classification by assigning error type tags to quantum error data as it is collected. The classical computing system proactively categorizes errors into distinct types (such as bit-flip, phase-flip, or amplitude damping errors) using predefined classification criteria. This preliminary tagging enables faster subsequent processing and correction, as the error type is already identified before correction algorithms are applied, thereby reducing overall processing time while maintaining high measurement precision.
3Reliability
If error correction data is processed without classification, then productivity is maintained, but reliability of error correction deteriorates
Solution Approach 1:
The system applies local quality by tailoring error correction processing to the specific type of error identified. Different error types (e.g., bit-flip vs. phase-flip errors) receive specialized correction protocols optimized for their characteristics. The classical computing system routes corrected error data to appropriate quantum devices based on error classification, ensuring that each error receives the most effective correction method. This localized approach improves correction accuracy without requiring a complete overhaul of the processing system, thereby maintaining productivity while enhancing reliability.
