qiskit.circuit.QuantumCircuit.snapshot_probabilities

QuantumCircuit.snapshot_probabilities(label, qubits, variance=False)

Take a probability snapshot of the simulator state.

Parameters

• label (str) – a snapshot label to report the result

• qubits (list) – the qubits to snapshot.

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

Returns

with attached instruction.

Return type

QuantumCircuit

Raises

ExtensionError – if snapshot is invalid.

Note

This method will be deprecated after the qiskit-aer 0.8 release. It has been superseded by the qiskit.providers.aer.library.save_probabilities() and qiskit.providers.aer.library.save_probabilities_dict() circuit methods.
