`pygsti.forwardsims.successfailfwdsim`

Defines the OplessForwardSimulator calculator class

Module Contents

A forward simulator that works with non-distributed CachedCOPALayout layouts.

class pygsti.forwardsims.successfailfwdsim.SuccessFailForwardSimulator(model=None)

A forward simulator that works with non-distributed CachedCOPALayout layouts.

This is just a small addition to ForwardSimulator, adding a persistent cache passed to new derived-class-overridable compute routines.

create_layout(circuits, dataset=None, resource_alloc=None, array_types=('E',), derivative_dimension=None, verbosity=0)

Constructs an circuit-outcome-probability-array (COPA) layout for circuits and dataset.

circuitslist: The circuits whose outcome probabilities should be computed.
datasetDataSet: The source of data counts that will be compared to the circuit outcome probabilities. The computed outcome probabilities are limited to those with counts present in dataset.
resource_allocResourceAllocation: A available resources and allocation information. These factors influence how the layout (evaluation strategy) is constructed.
array_typestuple, optional: A tuple of string-valued array types. See ForwardSimulator.create_layout().
derivative_dimensionint, optional: Optionally, the parameter-space dimension used when taking first and second derivatives with respect to the cirucit outcome probabilities. This must be non-None when array_types contains ‘ep’ or ‘epp’ types.
verbosityint or VerbosityPrinter: Determines how much output to send to stdout. 0 means no output, higher integers mean more output.
