SnapshotProbabilities

class SnapshotProbabilities(label, num_qubits, variance=False)

Bases : Snapshot

Snapshot instruction for all methods of Qasm simulator.

Create a probability snapshot instruction.

Paramètres

• label (str) – the snapshot label.

• num_qubits (int) – the number of qubits to snapshot.

• variance (bool) – compute variance of probabilities [Default: False]

Lève

ExtensionError – if snapshot is invalid.

Obsolète depuis la version 0.9.0: This instruction has been deprecated and will be removed no earlier than 3 months from the 0.9.0 release date. It has been superseded by the qiskit.providers.aer.library.SaveProbabilities and qiskit.providers.aer.library.SaveProbabilitiesDict instructions.
