cirq.qid_shape
Returns a tuple describing the number of quantum levels of each qubit/qudit/qid val
operates on.
cirq.qid_shape(
val: Any, default: TDefault = RaiseTypeErrorIfNotProvided
) -> Union[Tuple[int, ...], TDefault]
Used in the notebooks
Args |
val
|
The value to get the shape of.
|
default
|
Determines the fallback behavior when val doesn't have
a shape. If default is not set, a TypeError is raised. If
default is set to a value, that value is returned.
|
Returns |
If val has a _qid_shape_ method and its result is not
NotImplemented, that result is returned. Otherwise, if val has a
_num_qubits_ method, the shape with num_qubits qubits is returned
e.g. (2,)*num_qubits . If neither method returns a value other than
NotImplemented and a default value was specified, the default value is
returned.
|
Raises |
TypeError
|
val doesn't have either a _qid_shape_ or a _num_qubits_
method (or they returned NotImplemented) and also no default value
was specified.
