Wave and Particle Limit for Multiple Barrier Tunneling

Stefano De Leo, Pietro Rotelli

The particle approach to one-dimensional potential scattering is applied to non relativistic tunnelling between two, three and four identical barriers. We demonstrate as expected t…

A simple derivation of the Lindblad equation

Carlos Alexandre Brasil, Felipe Fernandes Fanchini, Reginaldo de Jesus Napolitano

We present a derivation of the Lindblad equation - an important tool for the treatment of non-unitary evolutions - that is accessible to undergraduate students in physics or mathem…

Why the Entanglement of Formation is not generally monogamic

F. F. Fanchini, M. C. de Oliveira, L. K. Castelano +1

Differently from correlation of classical systems, entanglement of quantum systems cannot be distributed at will - if one system A is maximally entangled with another system B, it…

How much time does a measurement take?

Carlos Alexandre Brasil, Leonardo Andreta de Castro, Reginaldo de Jesus Napolitano

We consider the problem of measurement using the Lindblad equation, which allows the introduction of time in the interaction between the measured system and the measurement apparat…

Laser cooling of a nanomechanical oscillator into its quantum ground state

Jasper Chan, T. P. Mayer Alegre, Amir H. Safavi-Naeini +5

A patterned Si nanobeam is formed which supports co-localized acoustic and optical resonances that are coupled via radiation pressure. Starting from a bath temperature of T=20K, th…

Locally Inaccessible Information as a Fundamental Ingredient to Quantum Information

F. F. Fanchini, L. K. Castelano, M. F. Cornelio +1

Quantum discord (QD) measures the fraction of the pairwise mutual information that is locally inaccessible, in a multipartite system. Fundamental aspects related to two important m…

Implementation of a two-qubit controlled-U gate based on unconventional geometric phase with a constant gating time

Bruno F. C. Yabu-uti, José A. Roversi

We propose an alternative scheme to implement a two-qubits Controlled-U gate in the hybrid system atom- (coupled cavities array). Our scheme results in a constant gating time…

Initial value representation for the SU(n) semiclassical propagator

Thiago F. Viscondi, Marcus A. M. de Aguiar

The semiclassical propagator in the representation of SU(n) coherent states is characterized by isolated classical trajectories subjected to boundary conditions in a doubled phase…

A New Phase Time Formula for Opaque Barrier Tunneling

Stefano De Leo, Vinicius Leonardi

After a brief review of the derivation of the standard phase time formula, based on the use of the stationary phase method, we propose, in the opaque limit, an alternative method t…

Local solutions of Maximum Likelihood Estimation in Quantum State Tomography

Douglas S. Gonçalves, Márcia A. Gomes-Ruggiero, Carlile Lavor +2

Maximum likelihood estimation is one of the most used methods in quantum state tomography, where the aim is to reconstruct the density matrix of a physical system from measurement…
