SaveStatevector

class SaveStatevector(num_qubits, label='statevector', pershot=False, conditional=False)

Save statevector

Create new instruction to save the simulator statevector.

Parameters:

• num_qubits (int) – the number of qubits

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

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

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

Note

This save instruction must always be performed on the full width of qubits in a circuit, otherwise an exception will be raised during simulation.
