SaveState

class SaveState(num_qubits, label=None, pershot=False, conditional=False)

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

Save simulator state

The format of the saved state depends on the simulation method used.

Create new instruction to save the simualtor state.

The format of the saved state depends on the simulation method used.

Parameters

• num_qubits (int) – the number of qubits of the

• label (str or None) – Optional, the key for retrieving saved data from results. If None the key will be the state type of the simulator.

• pershot (bool) – if True save a list of states for each shot of the simulation rather than a single state [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	Add classical condition on register or cbit classical and value val.
copy	Copy of the instruction.
inverse	Special case.
is_parameterized	Return True .IFF.
mirror	DEPRECATED: use instruction.reverse_ops().
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.
