Título: The computing power of anyonic linear optics

Abstract:  We generalize the FLO (Fermionic Linear Optics) model for one-dimensional systems of anyons in a linear chain and solve the Heisenberg equations for mode creation and annhilation operators with a number-preserving quadratic Hamiltonian. We define and describe beam-splitter and phase-shifter actions in general pairs of modes and prove that they change by the effect of a one-dimensional analog of the Aharonov-Bohm effect. We construct an entangling two-qubit gate with entanglement power dependent on the statistical parameter and prove that systems with any small deviation from fermionic statistics are universal for quantum computation.
