qiskit.pulse.SetPhase¶

class SetPhase(phase, channel, name=None)[código fonte]¶

The set phase instruction sets the phase of the proceeding pulses on that channel to phase radians.

In particular, a PulseChannel creates pulses of the form

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

The SetPhase instruction sets \(\phi\) to the instruction’s phase operand.

Instantiate a set phase instruction, setting the output signal phase on channel to phase [radians].

Parâmetros

phase (Union[complex, ParameterExpression]) – The rotation angle in radians.
channel (PulseChannel) – The channel this instruction operates on.
name (Optional[str]) – Display name for this instruction.

__init__(phase, channel, name=None)[código fonte]¶

Instantiate a set phase instruction, setting the output signal phase on channel to phase [radians].

Parâmetros

phase (Union[complex, ParameterExpression]) – The rotation angle in radians.
channel (PulseChannel) – The channel this instruction operates on.
name (Optional[str]) – Display name for this instruction.
