Legacy Operators

qiskit.aqua.operators.legacy

These are the Operators provided by Aqua up until the 0.6 release. These are being replaced by the operator flow function and we encourage you to use this.

Note

At some future time this legacy operator logic will be deprecated and removed.

Legacy Operators


`LegacyBaseOperator`	Operators relevant for quantum applications.
