Information and Computation: Classical and Quantum Aspects

A. Galindo, M. A. Martin-Delgado

Quantum theory has found a new field of applications in the realm of information and computation during the recent years. This paper reviews how quantum physics allows information…

The Majorization Arrow in Quantum Algorithm Design

J. I. Latorre, M. A. Martin-Delgado

We apply majorization theory to study the quantum algorithms known so far and find that there is a majorization principle underlying the way they operate. Grover's algorithm is a n…

Simple trace criterion for classification of multilayers

L. L. Sanchez-Soto, J. J. Monzon, T. Yonte +1

The action of any lossless multilayer is described by a transfer matrix that can be factorized in terms of three basic matrices. We introduce a simple trace criterion that classifi…

Single-particle nonlocality and entanglement with the vacuum

G. Bjork, P. Jonsson, L. L. Sanchez-Soto

We propose a single-particle experiment that is equivalent to the conventional two-particle experiment used to demonstrate a violation of Bell's inequalities. Hence, we argue that…

Comprehensive theory of the relative phase in atom-field interactions

J. Delgado, E. C. Yustas, L. L. Sanchez-Soto +1

We explore the role played by the quantum relative phase in a well-known model of atom-field interaction, namely, the Dicke model. We introduce an appropriate polar decomposition o…

Mimicking a Kerrlike medium in the dispersive regime of second-harmonic generation

A. B. Klimov, L. L. Sanchez-Soto, J. Delgado

We find an effective Hamiltonian describing the process of second-harmonic generation in the far-off resonant limit. We show that the dynamics of the fundamental mode is governed b…

Sub-wavelength lithography over extended areas

Gunnar Bjork, Luis L. Sanchez Soto, Jonas Soderholm

We demonstrate a systematic approach to sub-wavelength resolution lithographic image formation on films covering areas larger than a wavelength squared. For example, it is possible…
