save_amplitudes#

save_amplitudes(self, params, label='amplitudes', pershot=False, conditional=False)[source]#

Save complex statevector amplitudes.

Parameters:

  • params (List[int] or List[str]) – the basis states to return amplitudes for.

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

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

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

Returns:

with attached instruction.

Return type:

QuantumCircuit

Raises:

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