qiskit.optimization.QuadraticProgram.from_ising¶

QuadraticProgram.from_ising(qubit_op, offset=0.0, linear=False)[source]¶

Create a quadratic program from a qubit operator and a shift value.

Parameters

qubit_op (Union[OperatorBase, WeightedPauliOperator]) – The qubit operator of the problem.
offset (float) – The constant value in the Ising Hamiltonian.
linear (bool) – If linear is True, \(x^2\) is treated as a linear term since \(x^2 = x\) for \(x \in \{0,1\}\). Else, \(x^2\) is treat as a quadratic term. The default value is False.

Raises

QiskitOptimizationError – If there are Pauli Xs in any Pauli term
QiskitOptimizationError – If there are more than 2 Pauli Zs in any Pauli term
NotImplementedError – If the input operator is a ListOp

Return type

None
