A projection method for statics and dynamics of lattice spin systems

M. Kolesik, M. A. Novotny, P. A. Rikvold

A method based on Monte Carlo sampling of the probability flows projected onto the subspace of one or more slow variables is proposed for investigation of dynamic and static proper…

Center Vortices and the Asymptotic String Tension

L. Del Debbio, M. Faber, J. Greensite +1

We present a method for locating center vortices (``fluxons'') in thermalized lattice gauge field configurations. We find evidence, in lattice Monte Carlo simulations, that the asy…

Universal Algorithm for Optimal Estimation of Quantum States from Finite Ensembles

Radoslav Derka, Vladimir Buzek, Artur Ekert

We present a universal algorithm for the optimal quantum state estimation of an arbitrary finite dimensional system. The algorithm specifies a physically realizable positive operat…

Monte Carlo Simulation of Magnetization Reversal in Fe Sesquilayers on W(110)

M. Kolesik, M. A. Novotny, P. A. Rikvold

Iron sesquilayers grown at room temperature on W(110) exhibit a pronounced coercivity maximum near a coverage of 1.5 atomic monolayers. On lattices which faithfully reproduce the m…

Realization of nonlinear oscillators with a trapped ion

G. Drobny, B. Hladky

We consider a trapped ion with a quantized center-of-mass motion in 2D trap potential. With external laser fields the effective (non)linear coupling of two orthogonal vibrational m…

Excited pions, rho- and omega-mesons and their decays in a chiral SU(2) x SU(2) Lagrangian

M. K. Volkov, D. Ebert, M. Nagy

A chiral SU(2) x SU(2) Lagrangian containing, besides the usual meson fields, their first radial excitations is considered. The Lagrangian is derived by bosonization of the Nambu-J…

Quantum copying: A network

V. Buzek, S. L. Braunstein, M. Hillery +1

We present a network consisting of quantum gates which produces two imperfect copies of an arbitrary qubit. The quality of the copies does not depend on the input qubit. We also sh…

Reconstruction of quantum states of spin systems via the Jaynes principle of maximum entropy

V. Buzek, G. Drobny, G. Adam +2

We apply the Jaynes principle of maximum entropy for the partial reconstruction of correlated spin states. We determine the minimum set of observables which are necessary for the c…

From quantum Bayesian inference to quantum tomography

R. Derka, V. Buzek, G. Adam +1

We derive an expression for a density operator estimated via Bayesian quantum inference in the limit of an infinite number of measurements. This expression is derived under the ass…

Broadcasting of entanglement via local copying

V. Buzek, V. Vedral, M. B. Plenio +2

We show that inseparability of quantum states can be partially broadcasted (copied, cloned) with the help of local operations, i.e. distant parties sharing an entangled pair of spi…
