ExperimentSetting

class forest.benchmarking.observable_estimation.ExperimentSetting(in_state: forest.benchmarking.observable_estimation.TensorProductState, observable: pyquil.paulis.PauliTerm)

Input and output settings for an ObservablesExperiment.

Many near-term quantum algorithms and QCVV protocols take the following form:

• Start in a pauli state
• Do some interesting quantum circuit (e.g. prepare some ansatz)
• Measure the output of the circuit w.r.t. expectations of Pauli observables.

Where we typically use a large number of (start, measure) pairs but keep the quantum circuit program consistent. This class represents the (start, measure) pairs. Typically a large number of these ExperimentSetting objects will be created and grouped into a ObservablesExperiment.
