qiskit.circuit.library.QuadraticForm.required_result_qubits

static QuadraticForm.required_result_qubits(quadratic, linear, offset)

Get the number of required result qubits.

Parameters

• quadratic (Union[ndarray, List[List[float]]]) – A matrix containing the quadratic coefficients.

• linear (Union[ndarray, List[float]]) – An array containing the linear coefficients.

• offset (float) – A constant offset.

Return type

int

Returns

The number of qubits needed to represent the value of the quadratic form in twos complement.
