qiskit.quantum_info.SparsePauliOp.from_operator

static SparsePauliOp.from_operator(obj, atol=None, rtol=None)

Construct from an Operator objector.

Note that the cost of this construction is exponential as it involves taking inner products with every element of the N-qubit Pauli basis.

매개변수

• obj (Operator) – an N-qubit operator.

• atol (float) – Optional. Absolute tolerance for checking if coefficients are zero (Default: 1e-8).

• rtol (float) – Optional. relative tolerance for checking if coefficients are zero (Default: 1e-5).

반환
