qiskit.pulse.SetFrequency

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

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.

__init__(frequency, channel, name=None)[ソース]

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
