[BUG] Autoray wrongly dispatches `append` operation to `numpy` when using `pennylane.numpy.tensor` arrays #6119

Open EmilianoG-byte opened 2 months ago

EmilianoG-byte commented 2 months ago

Expected behavior

Appending two pennylane.numpy.tensor arrays using qml.math.append returns another pennylane.numpy.tensor array.

Actual behavior

Appending two pennylane.numpy arrays using qml.math.append returns a numpy.ndarray array.

Source code

import pennylane.numpy as pnp
a = pnp.array([0])
b = pnp.array([1])

type(qml.math.append(a,b))
>> numpy.ndarray
