Error Suppression

True-Q™ contains the following error suppression strategies:

  1. 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:

  2. Stochastic Calibration (SC)

    A protocol based on cycle benchmarking, which allows users to diagnose how errors affect specific components of density operators.

  3. 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.

  4. Noiseless Output Extrapolation (NOX)

    A protocol to extrapolate correct outputs from noisy circuits.
