ErrorGnoMark: Quantum Chip Error Diagnosis & Benchmark

Overview

ErrorGnoMark (Error Diagnose & Benchmark) is a comprehensive tool developed by the Quantum Operating System Group at the Beijing Academy of Quantum Information Sciences. It aims to provide a complete and thorough benchmark and diagnostic information for quantum chip¹², covering different layers of the quantum operating system: physical layer, quantum gate (circuit) layer, and application Layer. It evaluates key dimensions such as Scalability, Quality, and Speed³.

Potential Applications

ErrorGnoMark plays a crucial role in the journey toward building a fully functional quantum computer. Below are its key applications:

• Hardware Control: Facilitates quantum chip calibration, improves the reliability of simulators, and enables optimal quantum control.

• Compiler Optimization: Enhances compiler performance by leveraging error information, such as crosstalk, to optimize quantum gate operations.

• Cloud & Direct User Access: Enables precise real-time monitoring of chip performance (e.g., error rates) and supports advanced quantum error correction (QEC) experiments.

ErrorGnoMark offers a range of tutorials, from beginner to advanced topics. These tutorials are available on the official website, and users interested in research or development are encouraged to download and utilize Jupyter Notebooks.

Table of Contents

• Overview of Quantum Chip Errors: Technical adjustments, common issues, and solutions.

• Quantum Benchmarking:

  • Hardware Layer Characterization: Analyzing hardware performance metrics.
  • Quantum Gate (Circuit) Benchmarking²: Evaluating the fidelity and reliability of gate-level operations.
  • Quantum Chip Application Performance Testing: Testing and validating chip performance for practical applications.

• Databases for Benchmarking and Characterization: In the context of calibration, ErrorGnoMark focuses on combining {characterization + benchmarking} data to build two types of databases:

  • Characterization Data:

    • This data includes pulse-level control parameters such as (T_1) and (T_2) times and other metrics critical for understanding quantum hardware performance and limitations.

  • Benchmarking Data:

    • This data consists of various benchmark scores at the gate level, providing quantitative measures of gate performance and system reliability.

These databases are structured to distinguish between pulse-level and gate-level data:

• Gate-Level Compilation: Directly utilizes benchmarking data for gate optimization.

• Pulse-Level Compilation: Focuses on quantum optimal control, leveraging characterization data to fine-tune and enhance quantum operations.
