MatrixEvolution

qiskit.opflow.evolutions.MatrixEvolution GitHub(opens in a new tab)

Bases: EvolutionBase

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

Deprecated since version 0.24.0

The class qiskit.opflow.evolutions.matrix_evolution.MatrixEvolution is deprecated as of qiskit-terra 0.24.0. It will be removed in the Qiskit 1.0 release. For code migration guidelines, visit https://qisk.it/opflow_migration(opens in a new tab).


Methods

convert

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.

Returns

The converted operator.

Return type

OperatorBase
