qml.pow

pow(base, z=1, lazy=True, do_queue=True, id=None)

Raise an Operator to a power.

Parameters

• base (Operator) – the operator to be raised to a power

• z=1 (float) – the exponent

Keyword Arguments

• lazy=True (bool) – In lazy mode, all operations are wrapped in a Pow class and handled later. If lazy=False, operation-specific simplifications are first attempted.

• do_queue (bool) – indicates whether the operator should be recorded when created in a tape context

• id (str) – custom label given to an operator instance, can be useful for some applications where the instance has to be identified

Returns

Operator

Example

>>> qml.pow(qml.PauliX(0), 0.5)
PauliX(wires=[0])**0.5
>>> qml.pow(qml.PauliX(0), 0.5, lazy=False)
SX(wires=[0])
>>> qml.pow(qml.PauliX(0), 0.1, lazy=False)
PauliX(wires=[0])**0.1
>>> qml.pow(qml.PauliX(0), 2, lazy=False)
Identity(wires=[0])

Lazy behavior can also be accessed via op ** z.
