SaveAmplitudesSquared

class SaveAmplitudesSquared(num_qubits, params, label='amplitudes_squared', unnormalized=False, pershot=False, conditional=False)

Bases: qiskit.providers.aer.library.save_instructions.save_data.SaveAverageData

Save squared statevector amplitudes (probabilities).

Instruction to save squared statevector amplitudes (probabilities).

Parameter

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

• params (list) – list of entries to vale.

• label (str) – the key for retrieving saved data from results.

• unnormalized (bool) – If True return save the unnormalized accumulated probabilities over all shots [Default: False].

• pershot (bool) – if True save a list of probability vectors for each shot of the simulation rather than the a single amplitude vector [Default: False].

• conditional (bool) – if True save the probability vector conditional on the current classical register values [Default: False].

Verursacht

ExtensionError – if params is invalid for the specified number of qubits.
