MatrixEvolution
class qiskit.opflow.evolutions.MatrixEvolution
Bases: EvolutionBase
Deprecated: Performs Evolution by classical matrix exponentiation, constructing a circuit with UnitaryGates or HamiltonianGates containing the exponentiation of the Operator.
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.
