qml.noise.wires_eq¶
-
wires_eq
(wires)[source]¶ Builds a conditional as a
BooleanFn
for evaluating if a given wire is equal to specified set of wires.- Parameters
wires (Union(Iterable[int, str], Wires, Operation, int, str)) – Object to be used for building the wire set.
- Returns
A callable object with signature
Union(Iterable[int, str], Wires, Operation, int, str)
. It evaluates toTrue
if the wire set constructed from the input to the callable is equal to the one built from the specifiedwires
set.- Return type
- Raises
ValueError – If the wire set cannot be computed from
wires
.
Example
One may use
wires_eq
with a given sequence of wires which are used as a wire set:>>> cond_func = qml.noise.wires_eq(0) >>> cond_func(qml.X(0)) True
>>> cond_func(qml.RY(1.23, wires=[3])) False
Additionally, if an
Operation
is provided, itswires
are extracted and used to build the wire set:>>> cond_func = qml.noise.wires_eq(qml.RX(1.0, "dino")) >>> cond_func(qml.RZ(1.23, wires="dino")) True
>>> cond_func("eve") False
