TwirlingOptions

class TwirlingOptions(*args, **kwargs)

Twirling options.

Parameters

• enable_gates – Whether to apply 2-qubit gate twirling. Default: False.

• enable_measure – Whether to enable twirling of expectation value measurements in Estimator. Default: True.

• num_randomizations – The number of random samples to use when twirling or peforming sampled mitigation. If “auto”, the value will be chosen automatically based on the input PUBs. Default: “auto”.

• shots_per_randomization – The number of shots to run for each random sample. If “auto”, the value will be chosen automatically based on the input PUBs. Default: “auto”.

• strategy –

  Specify the strategy of twirling qubits in identified layers of 2-qubit twirled gates. Allowed values are

  • If "active" only the instruction qubits in each individual twirled layer will be twirled.
  • If "active-circuit" the union of all instruction qubits in the circuit will be twirled in each twirled layer.
  • If "active-accum" the union of instructions qubits in the circuit up to the current twirled layer will be twirled in each individual twirled layer.
  • If "all" all qubits in the input circuit will be twirled in each twirled layer.

  Default: “active-accum”.
