qiskit.pulse.Schedule.replace

Schedule.replace(old, new, inplace=False)

Return a Schedule with the old instruction replaced with a new instruction.

The replacement matching is based on an instruction equality check.

from qiskit import pulse

d0 = pulse.DriveChannel(0)

sched = pulse.Schedule()

old = pulse.Play(pulse.Constant(100, 1.0), d0)
new = pulse.Play(pulse.Constant(100, 0.1), d0)

sched += old

sched = sched.replace(old, new)

assert sched == pulse.Schedule(new)

Only matches at the top-level of the schedule tree. If you wish to perform this replacement over all instructions in the schedule tree. Flatten the schedule prior to running:

.. jupyter-execute::

sched = pulse.Schedule()

sched += pulse.Schedule(old)

sched = sched.flatten()

sched = sched.replace(old, new)

assert sched == pulse.Schedule(new)

প্যারামিটার

• old (Union[Schedule, Instruction]) -- Instruction to replace.

• new (Union[Schedule, Instruction]) -- Instruction to replace with.

• inplace (bool) -- Replace instruction by mutably modifying this Schedule.
