SetFrequency¶

class SetFrequency(frequency, channel, name=None)[ソース]¶

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

Set the channel frequency. This instruction operates on PulseChannel s. A PulseChannel creates pulses of the form

\[Re[\exp(i 2\pi f jdt + \phi) d_j].\]

Here, \(f\) is the frequency of the channel. The instruction SetFrequency allows the user to set the value of \(f\). All pulses that are played on a channel after SetFrequency has been called will have the corresponding frequency.

The duration of SetFrequency is 0.

Creates a new set channel frequency instruction.

パラメータ

frequency (Union[float, ParameterExpression]) – New frequency of the channel in Hz.
channel (PulseChannel) – The channel this instruction operates on.
name (Optional[str]) – Name of this set channel frequency instruction.

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.
`ch_stop_time`	Return maximum 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.
