qiskit.quantum_info.Operator.from_label

classmethod Operator.from_label(label)

Return a tensor product of single-qubit operators.

Parâmetros

label (string) – single-qubit operator string.

Retorno

The N-qubit operator.

Tipo de retorno

Operator

Levanta

QiskitError – if the label contains invalid characters, or the length of the label is larger than an explicitly specified num_qubits.

Additional Information:

The labels correspond to the single-qubit matrices: “I”: [[1, 0], [0, 1]] “X”: [[0, 1], [1, 0]] “Y”: [[0, -1j], [1j, 0]] “Z”: [[1, 0], [0, -1]] “H”: [[1, 1], [1, -1]] / sqrt(2) “S”: [[1, 0], [0 , 1j]] “T”: [[1, 0], [0, (1+1j) / sqrt(2)]] “0”: [[1, 0], [0, 0]] “1”: [[0, 0], [0, 1]] “+”: [[0.5, 0.5], [0.5 , 0.5]] “-“: [[0.5, -0.5], [-0.5 , 0.5]] “r”: [[0.5, -0.5j], [0.5j , 0.5]] “l”: [[0.5, 0.5j], [-0.5j , 0.5]]
