Description
Expected behavior
Raising a TShift operator to the power of 2 should return something.
Actual behavior
The current implementation of pow on the TShift operator is given by
def pow(self, z):
return super().pow(z % 3)
which calls the pow method on the Operator class, given by
if z == 0:
return []
if z == 1:
if QueuingManager.recording():
return [qml.apply(self)]
return [copy.copy(self)]
raise PowUndefinedError
So, attempting to raise a TShift to the power of 2 results in a PowUndefinedError.
