True-Q™ contains the following error suppression strategies:
- Randomized Compiling (RC)
A protocol which compiles circuits into a form where coherent noise is suppressed without adding depth to the circuit, that is, without increasing the number of cycles needed to implement the circuit. We provide the following examples that show how RC can be used in practice:
- Example: Running Randomized Compiling
Covers the fundamentals of how Randomized Compiling works in True-Q™
- Example: Customizing Randomized Compiling with Cycle Markers
Shows how RC can be customized to only act on specified cycles.
- Example: Randomized Compilation with different Compilation Options
Demonstrates more advanced features of RC, including its use with non-Clifford entangling gates, randomized measurements, and incorporating RC through explicit use of the
Compilerrather than through the simple
- Example: Randomly compiling arbitrary multi-qubit gates
Demonstrates how to use the
RCKakcompiler pass to handle circuits containing non-Clifford multi-qubit gates without an additional decomposition step.
- Readout Calibration (RCAL)
Diagnose state-dependent readout errors. The results can also be used to correct readout errors for other diagnostic tools.
- Example: Running Readout Calibration
Walks through the implementation of readout calibration for qubits and qutrits and shows how the correction can be automatically applied to a collection of circuits.
