Snapshot¶

class Snapshot(label, snapshot_type='statevector', name=None)[código fonte]¶

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 to label. This parameter is only for display purposes and is not taken into account during comparison.

Levanta

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`.
`ch_duration`	Return duration of the supplied channels in this Instruction.
`ch_start_time`	Return minimum start time for supplied channels.
`ch_stop_time`	Return maximum start time for supplied channels.
`draw`	Plot the 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.
