Classical to quantum in large number limit
Kavan Modi, Rosario Fazio, Saverio Pascazio +2
We construct a quantumness witness following the work of Alicki and van Ryn (AvR) in "A simple test of quantumness for a single system" [J. Phys. A: Math. Theor., vol. 41, 062001 (…
High-fidelity quantum driving
Mark G. Bason, Matthieu Viteau, Nicola Malossi +7
The ability to accurately control a quantum system is a fundamental requirement in many areas of modern science such as quantum information processing and the coherent manipulation…
Generating topological order from a 2D cluster state using a duality mapping
Benjamin J. Brown, Wonmin Son, Christina V. Kraus +2
In this paper we prove, extend and review possible mappings between the two-dimensional Cluster state, Wen's model, the two-dimensional Ising chain and Kitaev's toric code model. W…
Staying adiabatic with unknown energy gap
J. Nehrkorn, S. Montangero, A. Ekert +3
We introduce an algorithm to perform an optimal adiabatic evolution that operates without an apriori knowledge of the system spectrum. By probing the system gap locally, the algori…
Statistical mechanics of the Cluster-Ising model
Pietro Smacchia, Luigi Amico, Paolo Facchi +4
We study a Hamiltonian system describing a three-spin-1/2 cluster-like interaction competing with an Ising-like anti-ferromagnetic interaction. We compute free energy, spin correla…
Quantum phase transition between cluster and antiferromagnetic states
Wonmin Son, Luigi Amico, Rosario Fazio +3
We study a Hamiltonian system describing a three spin-1/2 cluster-like interaction competing with an Ising-like exchange. We show that the ground state in the cluster phase possess…
Stiffness in 1D Matrix Product States with periodic boundary conditions
Davide Rossini, Vittorio Giovannetti, Rosario Fazio
We discuss in details a modified variational matrix-product-state algorithm for periodic boundary conditions, based on a recent work by P. Pippan, S.R. White and H.G. Everts, Phys.…
