The self-induced approach to decoherence in cosmology
Mario Castagnino, Olimpia Lombardi
In this paper we will present the \QTR{it}{self-induced approach} to decoherence, which does not require the interaction between the system and the environment: decoherence in clos…
The cosmological origin of time-asymmetry
Mario Castagnino, Luis Lara, Olimpia Lombardi
In this paper we address the problem of the arrow of time from a cosmological point of view, rejecting the traditional entropic approach that defines the future direction of time a…
Casimir interaction between two concentric cylinders: exact versus semiclassical results
Francisco D. Mazzitelli, María J. Sánchez, Norberto N. Scoccola +1
The Casimir interaction between two perfectly conducting, infinite, concentric cylinders is computed using a semiclassical approximation that takes into account families of classic…
Quantum electromagnetic field in a three dimensional oscillating cavity
Martin Crocce, Diego A. R. Dalvit, Francisco D. Mazzitelli
We compute the photon creation inside a perfectly conducting, three dimensional oscillating cavity, taking the polarization of the electromagnetic field into account. As the bounda…
Discrete Wigner functions and the phase space representation of quantum teleportation
Juan Pablo Paz
We present a phase space description of the process of quantum teleportation for a system with an dimensional space of states. For this purpose we define a discrete Wigner func…
Quantum computers in phase space
Cesar Miquel, Juan Pablo Paz, Marcos Saraceno
We represent both the states and the evolution of a quantum computer in phase space using the discrete Wigner function. We study properties of the phase space representation of qua…
