Entanglement in the dispersive interaction of trapped ions with a quantized field

F. L. Semião, K. Furuya

The mode-mode entanglement between trapped ions and cavity fields is investigated in the dispersive regime. We show how a simple initial preparation of Gaussian coherent states and…

Two-photon interaction between trapped ions and cavity fields

F. L. Semião, A. Vidiella-Barranco

In this paper, we generalize the ordinary two-photon Jaynes-Cummings model (TPJCM) by considering the atom (or ion) to be trapped in a simple harmonic well. A typical setup would b…

Quantum channels in random spin chains

Jose A. Hoyos, Gustavo Rigolin

We study the entanglement between pairs of qubits in a random antiferromagnetic spin-1/2 chain at zero temperature. We show that some very distant pairs of qubits are highly entang…

Quantification of Continuous Variable Entanglement with only Two Types of Simple Measurements

Gustavo Rigolin, Marcos C. de Oliveira

Here we propose an experimental set-up in which it is possible to measure the entanglement of a two-mode Gaussian state, be it pure or mixed, using only simple linear optical devic…

Unconditional Bell-type state generation for spatially separate trapped ions

F. L. Semião, R. J. Missori, K. Furuya

We propose a scheme for generation of maximally entangled states involving internal electronic degrees of freedom of two distant trapped ions, each of them located in a cavity. Thi…

Coherent State Path Integrals in the Weyl Representation

L. C. dos Santos, M. A. M. de Aguiar

We construct a representation of the coherent state path integral using the Weyl symbol of the Hamiltonian operator. This representation is very different from the usual path integ…

Quantum Computation via Paraconsistent Computation

Juan C. Agudelo, Walter Carnielli

We present an original model of paraconsistent Turing machines (PTMs), a generalization of the classical Turing machines model of computation using a paraconsistent logic. Next, we…

A semiclassical trace formula for the canonical partition function of one dimensional systems

Fernando Parisio, M. A. M. de Aguiar

We present a semiclassical trace formula for the canonical partition function of arbitrary one-dimensional systems. The approximation is obtained via the stationary exponent method…

Quantum Dissipation and Decoherence via Interaction with Low-Dimensional Chaos: a Feynman-Vernon Approach

M. V. S. Bonanca, M. A. M. de Aguiar

We study the effects of dissipation and decoherence induced on a harmonic oscillator by the coupling to a chaotic system with two degrees of freedom. Using the Feynman-Vernon appro…

Operational Classification and Quantification of Multipartite Entangled States

Gustavo Rigolin, Thiago R. de Oliveira, Marcos C. de Oliveira

We formalize and extend an operational multipartite entanglement measure introduced by T. R. Oliveira, G. Rigolin, and M. C. de Oliveira, Phys. Rev. A 73, 010305(R) (2006), through…

Generalized Quantum State Sharing

Goren Gordon, Gustavo Rigolin

We present two quantum state sharing protocols where the channels are not maximally entangled states. By properly choosing the measurement basis it is possible to achieve unity fid…

Decoherence induced by a phase-damping reservoir

R. M. Angelo, E. S. Cardoso, K. Furuya

A phase damping reservoir composed by -bosons coupled to a system of interest through a cross-Kerr interaction is proposed and its effects on quantum superpo sitions are investi…

Optimal Conditions for Atomic Homodyne Detection on Bose-Einstein Condensates

B. R. da Cunha, M. C. de Oliveira

The dynamics of a two-mode Bose-Einstein condensate trapped in a double-well potential results approximately in an effective Rabi oscillation regime of exchange of population betwe…

Dissipative Stern-Gerlach recombination experiment

Thiago R. Oliveira, A. O. Caldeira

The possibility of obtaining the initial pure state in a usual Stern-Gerlach experiment through the recombination of the two emerging beams is investigated. We have extended the pr…
