True-Q™ provides a wide variety of error diagnostic protocols to characterize quantum hardware that range from benchmarking of individual operations to benchmarking entire cycles and circuits.
The following pages cover both the basic and advanced usage of True-Q™ protocols.
- Choosing the Appropriate Diagnostic Tool
Outlines the basic types of protocols and helps the user get started with the diagnostic tools.
- Introduction to Protocols
Provides a more in-depth introduction into how the error diagnostic protocols work in True-Q™.
- Selecting Parameters for Error Diagnostics
Gives an overview of the simple input parameters to protocols and how their value affect the results.
- Selecting Parameters for Error Diagnostics (Advanced)
Covers the full set of parameters for all diagnostic protocols.
True-Q™'s error diagnostic protocols are listed below. For each protocol, we provide the theoretical background alongside with a hands-on example that shows how to run the protocol in the software.
- Extended Randomized Benchmarking (XRB) and Example: Running XRB
Enables users to distinguish systematic (coherent) errors from stochastic errors (such as decoherence, dephasing, and rapid fluctuations in control frequencies) in combination with SRB. See Example: Comparing Infidelities with SRB and XRB for how these two protocols can be combined.
Composite protocols leverage more basic diagnostic protocols to provide higher-level assessments of quantum hardware performance. True-Q™ currently contains two composite protocols:
