The Weyl quantization of classical observables on the torus (as phase space)\nwithout regularity assumptions is explicitly computed. The equivalence class of\nsymbols yielding the same Weyl operator is characterized. The Heisenberg\nequation for the dynamics of general quantum observables is written through the\nMoyal brackets on the torus and the support of the Wigner transform is\ncharacterized. Finally, a dequantization procedure is introduced that applies,\nfor instance, to the Pauli matrices. As a result we obtain the corresponding\nclassical symbols.\n
