  In this paper, we show that a qutrit version of ZX-calculus, with rules
significantly different from that of the qubit version, is complete for pure
qutrit stabilizer quantum mechanics, where state preparations and measurements
are based on the three dimensional computational basis, and unitary operations
are required to be in the generalized Clifford group. This means that any
equation of diagrams that holds true under the standard interpretation in
Hilbert spaces can be derived diagrammatically. In contrast to the qubit case,
the situation here is more complicated due to the richer structure of this
qutrit ZX-calculus.
