Snapshot

class Snapshot(label, snapshot_type='statevector', name=None)

ベースクラス: qiskit.pulse.instructions.instruction.Instruction

An instruction targeted for simulators, to capture a moment in the simulation.

Create new snapshot.

パラメータ

• label (str) – Snapshot label which is used to identify the snapshot in the output.

• snapshot_type (str) – Type of snapshot, e.g., “state” (take a snapshot of the quantum state). The types of snapshots offered are defined by the simulator used.

• name (Optional[str]) – Snapshot name which defaults to label. This parameter is only for display purposes and is not taken into account during comparison.

例外

PulseError – If snapshot label is invalid.

Methods

append	Return a new Schedule with schedule inserted at the maximum time over all channels shared between self and schedule.
assign_parameters	Modify and return self with parameters assigned according to the input.
ch_duration	Return duration of the supplied channels in this Instruction.
ch_start_time	Return minimum start time for supplied channels.

draw	Plot the instruction.
flatten	Return itself as already single instruction.
insert	Return a new Schedule with schedule inserted within self at start_time.
is_parameterized	Return True iff the instruction is parameterized.
shift	Return a new schedule shifted forward by time.
