from_ising(qubit_op, offset=0.0, linear=False)

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

Variables are mapped to qubits in the same order, i.e., i-th variable is mapped to i-th qubit. See https://github.com/Qiskit/qiskit-terra/issues/1148 for details.

প্যারামিটার:

• qubit_op (BaseOperator) -- The qubit operator of the problem.

• offset (float) -- The constant term in the Ising Hamiltonian.

• linear (bool) -- If linear is True, $x^2$ is treated as a linear term since $x^2=x$ for $x\in \{0,1\}$. Otherwise, $x^2$ is treat as a quadratic term. The default value is False.

রিটার্নস:

The quadratic program corresponding to the qubit operator.

রেইজেস:

• QiskitOptimizationError -- if there are Pauli Xs or Ys in any Pauli term

• QiskitOptimizationError -- if there are more than 2 Pauli Zs in any Pauli term

• QiskitOptimizationError -- if any Pauli term has an imaginary coefficient
