Three-Qubit Entangled Embeddings of CPT and Dirac Groups within E 8 Weyl Group

Abstract: In quantum information context, the groups generated by Pauli spin matrices, and Dirac gamma matrices, are known as the single qubit Pauli group P, and two-qubit Pauli group P 2 , respectively. It has been found (Socolovsky, Int. J. Theor. Phys. 43: 1941 that the CPT group of the Dirac equation is isomorphic to P. One introduces a two-qubit entangling orthogonal matrix S basically related to the CPT symmetry. With the aid of the two-qubit swap gate, the S matrix allows the generation of the three-qubit real Cl… Show more

“…5) is put forward. Earlier papers of one of the authors focused on the three-qubit realization of Coxeter groups, such as the largest one W (E 8 ), together with its most relevant subgroups comprising the three-qubit Clifford group C + 3 , W (E 7 ), W (E 6 ), W (F 4 ) and other subgroups [7,9]. Here, one discovers that the twoqubit real entangling gate S 2 [see Eq.…”
