Topological order in 1D Cluster state protected by symmetry
Wonmin Son, Luigi Amico, Vlatko Vedral
We demonstrate how to construct the Z2*Z2 global symmetry which protects the ground state degeneracy of cluster states for open boundary conditions. Such a degeneracy ultimately ar…
Optimal correlations in many-body quantum systems
Luigi Amico, Davide Rossini, Alioscia Hamma +1
Information and correlations in a quantum system are closely related through the process of measurement. We explore such relation in a many-body quantum setting, effectively bridgi…
Role of covalent and metallic intercalation on the electronic properties of epitaxial graphene on SiC(0001)
I. Deretzis, A. La Magna
We present an orbital-resolved density functional theory study on the electronic properties of hydrogen and lithium intercalated graphene grown on the Si face of SiC. Starting from…
Correlation between microstructure deflections and film/substrate curvature under generalized stress fields
Massimo Camarda, Ruggero Anzalone, Giuseppe D'Arrigo +5
In this article we develop an analytical theory that correlates the macroscopic curvature of stressed film/substrate systems with the microscopic in-plane and out-of-plane deflecti…
Superconducting qubit manipulated by fast pulses: experimental observation of distinct decoherence regimes
F. Chiarello, E. Paladino, M. G. Castellano +4
A particular superconducting quantum interference device (SQUID)qubit, indicated as double SQUID qubit, can be manipulated by rapidly modifying its potential with the application o…
Optimal operating conditions of an entangling two-transmon gate
A. D'Arrigo, E. Paladino
We identify optimal operating conditions of an entangling two-qubit gate realized by a capacitive coupling of two superconducting charge qubits in a transmission line resonator (th…
