dq.xyz

xyz(*, layout: Layout | None = None) -> QArray

Returns the Pauli \(\sigma_x\), \(\sigma_y\) and \(\sigma_z\) operators.

Parameters

• layout –

  Matrix layout (dq.dense, dq.dia or None).

Returns

(qarray of shape (3, 2, 2)) Pauli \(\sigma_x\), \(\sigma_y\) and \(\sigma_z\) operators.

Examples

>>> dq.xyz()
QArray: shape=(3, 2, 2), dims=(2,), dtype=complex64, layout=dia, ndiags=3

  [ 1.+0.j    ⋅   ]]

 [[   ⋅     0.-1.j]
  [ 0.+1.j    ⋅   ]]

 [[ 1.+0.j    ⋅   ]
  [   ⋅    -1.+0.j]]]
