- class qiskit.pulse.instructions.ShiftPhase(phase, channel, name=None)#
The shift phase instruction updates the modulation phase of proceeding pulses played on the same
Channel. It is a relative increase in phase determined by the
In particular, a PulseChannel creates pulses of the form\[Re[\exp(i 2\pi f jdt + \phi) d_j].\]
ShiftPhaseinstruction causes \(\phi\) to be increased by the instruction's
phaseoperand. This will affect all pulses following on the same channel.
The qubit phase is tracked in software, enabling instantaneous, nearly error-free Z-rotations by using a ShiftPhase to update the frame tracking the qubit state.

Return a new
scheduleinserted at the maximum time over all channels shared between
Return duration of the supplied channels in this Instruction.

- draw(dt=1, style=None, filename=None, interp_method=None, scale=1, plot_all=False, plot_range=None, interactive=False, table=True, label=False, framechange=True, channels=None)#
Plot the instruction.
Deprecated since version 0.23.0: The method
qiskit.pulse.instructions.instruction.Instruction.draw()is deprecated as of qiskit-terra 0.23.0. It will be removed no earlier than 3 months after the release date. No direct alternative is being provided to drawing individual pulses. But, instructions can be visualized as part of a complete schedule using
dt (float) -- Time interval of samples
style (Optional[SchedStyle]) -- A style sheet to configure plot appearance
filename (str | None) -- Name required to save pulse image
interp_method (Callable | None) -- A function for interpolation
scale (float) -- Relative visual scaling of waveform amplitudes
plot_all (bool) -- Plot empty channels
interactive (bool) -- When set true show the circuit in a new window (this depends on the matplotlib backend being used supporting this)
table (bool) -- Draw event table for supported instructions
label (bool) -- Label individual instructions
framechange (bool) -- Add framechange indicators
