qiskit.opflow.evolutions.EvolutionBase

class EvolutionBase

A base for Evolution converters. Evolutions are converters which traverse an Operator tree, replacing any EvolvedOp e with a Schrodinger equation-style evolution CircuitOp equalling or approximating the matrix exponential of -i * the Operator contained inside (e.primitive). The Evolutions are essentially implementations of Hamiltonian Simulation algorithms, including various methods for Trotterization.

__init__()

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__()	Initialize self.
convert(operator)	Traverse the operator, replacing any EvolutionOps with their equivalent evolution CircuitOps.

abstract convert(operator)

Traverse the operator, replacing any EvolutionOps with their equivalent evolution CircuitOps.

Args:

operator: The Operator to convert.

Return type

OperatorBase

Returns

The converted Operator, with EvolutionOps replaced by CircuitOps.
