Abstract The commutation relations of the generalized Pauli operators of a qubit–qutrit system are discussed in the newly established graph-theoretic and finite-geometrical settings. The dual of the Pauli graph of this system is found to be isomorphic to the projective line over the product ring $\mathcal{Z}_{2}\times\mathcal{Z}_{3}$ . A “peculiar” feature in comparison with two-qubits is that two distinct points/operators can be joined by more than one line. The multi-line property is shown… Expand

A Sequence of Qubit-Qudit Pauli Groups as a Nested Structure of Doilies
Following the spirit of a recent work of one of the authors (J. Phys. A: Math. Theor. 44 (2011) 045301), the essential structure of the generalized Pauli group of a qubit-qu$d$it, where $d = 2^{k}$Expand
On the Pauli graphs on N-qudits
TLDR
