PecOptions

class PecOptions(max_overhead=Unset, noise_gain=Unset)[source]

Bases: object

Probabalistic error cancellation mitigation options. This is only used by V2 Estimator.

Attributes

Parameters:

  • max_overhead (UnsetType | float | None)

  • noise_gain (UnsetType | float | Literal['auto'])

max_overhead: UnsetType | float | None = Unset

The maximum circuit sampling overhead allowed, or None for no maximum.

Default: 100.

noise_gain: UnsetType | float | Literal['auto'] = Unset

The amount by which to scale the noise, where:

  • A value of 0 corresponds to removing the full learned noise.

  • A value of 1 corresponds to no removal of the learned noise.

  • A value between 0 and 1 corresponds to partially removing the learned noise.

  • A value greater than one corresponds to amplifying the learned noise.

If “auto”, the value in the range [0, 1] will be chosen automatically for each input PUB based on the learned noise strength, max_overhead, and the depth of the PUB.

Default: “auto”.
