qiskit.opflow.evolutions.MatrixEvolution

class MatrixEvolution

Performs Evolution by classical matrix exponentiation, constructing a circuit with UnitaryGates or HamiltonianGates containing the exponentiation of the Operator.

__init__()

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

Methods

__init__()	Initialize self.
convert(operator)	Traverse the operator, replacing EvolvedOps with CircuitOps containing UnitaryGates or HamiltonianGates (if self.coeff is a ParameterExpression) equalling the exponentiation of -i * operator.

convert(operator)

Traverse the operator, replacing EvolvedOps with CircuitOps containing UnitaryGates or HamiltonianGates (if self.coeff is a ParameterExpression) equalling the exponentiation of -i * operator. This is done by converting the EvolvedOp.primitive to a MatrixOp and simply calling .exp_i() on that.

Parameters

operator (OperatorBase) – The Operator to convert.

Return type

OperatorBase

Returns

The converted operator.
