(Color online) Representation of a set of encoded input states. (a) A Bloch sphere where different planes are marked with
color codes. The green circle marks the
X-Z plane, the red circle marks the X-Y plane, and the blue circle marks the Y-Z plane. (b)–(d) The encoded input states are shown in the correspondent plane of the Bloch sphere. For a complete definition of the chosen
states.
