Snapshot

class Snapshot(label, snapshot_type='statevector', num_qubits=0, num_clbits=0, params=None)

기반 클래스: qiskit.circuit.instruction.Instruction

Simulator snapshot instruction.

Create new snapshot instruction.

매개변수

• label (str) – the snapshot label for result data.

• snapshot_type (str) – the type of the snapshot.

• num_qubits (int) – the number of qubits for the snapshot type [Default: 0].

• num_clbits (int) – the number of classical bits for the snapshot type [Default: 0].

• params (list or None) – the parameters for snapshot_type [Default: None].

예외

ExtensionError – if snapshot label is invalid.

버전 0.9.0부터 폐지: This instruction has been deprecated and will be removed no earlier than 3 months from the 0.9.0 release date. It has been superseded by the save instructions in qiskit.providers.aer.library module.
