SaveStatevector

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

Bases: qiskit_aer.library.save_instructions.save_data.SaveSingleData

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.

Methods

add_decomposition	Add a decomposition of the instruction to the SessionEquivalenceLibrary.
assemble	Return the QasmQobjInstruction for the intructions.
broadcast_arguments	Validation of the arguments.
c_if	Set a classical equality condition on this instruction between the register or cbit classical and value val.
copy	Copy of the instruction.
inverse	Special case.
is_parameterized	Return True .IFF.
qasm	Return a default OpenQASM string for the instruction.
repeat	Creates an instruction with gate repeated n amount of times.
reverse_ops	For a composite instruction, reverse the order of sub-instructions.
soft_compare	Soft comparison between gates.
validate_parameter	Instruction parameters has no validation or normalization.
