Snapshot¶
- class Snapshot(label, snapshot_type='statevector', name=None)[código fonte]¶
Bases:
Instruction
An instruction targeted for simulators, to capture a moment in the simulation.
Create new snapshot.
- Parâmetros
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 tolabel
. This parameter is only for display purposes and is not taken into account during comparison.
Methods
Return a new
Schedule

inserted at the maximum time over all channels shared betweenself
andschedule
.Return duration of the supplied channels in this Instruction.
Return minimum start time for supplied channels.
Return maximum start time for supplied channels.
Plot the instruction.
Return a new
Schedule
withschedule
inserted withinself
atstart_time
.Return True iff the instruction is parameterized.
Return a new schedule shifted forward by time.
