Magic informationally complete POVMs with permutations

Quantum Physics 2018-01-12 v3

Abstract

Eigenstates of permutation gates are either stabilizer states (for gates in the Pauli group) or magic states, thus allowing universal quantum computation [M. Planat and Rukhsan-Ul-Haq, Preprint 1701.06443]. We show in this paper that a subset of such magic states, when acting on the generalized Pauli group, define (asymmetric) informationally complete POVMs. Such IC-POVMs, investigated in dimensions 22 to 1212, exhibit simple finite geometries in their projector products and, for dimensions 44 and 88 and 99, relate to two-qubit, three-qubit and two-qutrit contextuality.
