PrimitiveOp¶
- class PrimitiveOp(primitive, coeff=1.0)[소스]¶
기반 클래스:
OperatorBase
Deprecated: A class for representing basic Operators, backed by Operator primitives from Terra. This class (and inheritors) primarily serves to allow the underlying primitives to 《flow》 - i.e. interoperability and adherence to the Operator formalism - while the core computational logic mostly remains in the underlying primitives. For example, we would not produce an interface in Terra in which
QuantumCircuit1 + QuantumCircuit2
equaled the Operator sum of the circuit unitaries, rather than simply appending the circuits. However, within the Operator flow summing the unitaries is the expected behavior.Note that all mathematical methods are not in-place, meaning that they return a new object, but the underlying primitives are not copied.
버전 0.24.0부터 폐지됨: The class
qiskit.opflow.primitive_ops.primitive_op.PrimitiveOp
is deprecated as of qiskit-terra 0.24.0. It will be removed no earlier than 3 months after the release date. For code migration guidelines, visit https://qisk.it/opflow_migration.- 매개변수
primitive (Union[Instruction, QuantumCircuit, List, ndarray, spmatrix, Operator, Pauli, SparsePauliOp]) – The operator primitive being wrapped.
coeff (Union[complex, ParameterExpression]) – A coefficient multiplying the primitive.
