cirq.eye_tensor

Returns an identity matrix reshaped into a tensor.

cirq.eye_tensor(
    half_shape: Tuple[int, ...], *, dtype: 'DTypeLike'
) -> np.ndarray

Args
`half_shape`	A tuple representing the number of quantum levels of each qubit the returned matrix applies to. `half_shape` is (2, 2, 2) for a three-qubit identity operation tensor.
`dtype`	The numpy dtype of the new array.

Returns
The created numpy array with shape `half_shape + half_shape`.
