Anomalous diffusion in the resonant quantum kicked rotor
A. Romanelli, Guzmán Hernández
We study the resonances of the quantum kicked rotor subjected to an excitation that follows a deterministic time-dependent prescription. For the primary resonances we find an analy…
Driving quantum walk spreading with the coin operator
Alejandro Romanelli
We generalize the discrete quantum walk on the line using a time dependent unitary coin operator. We find an analytical relation between the long-time behaviors of the standard dev…
Decoherence without classicality in the resonant quantum kicked rotor
A. Romanelli
We study the quantum kicked rotor in resonance subjected to an unitary noise defined through Kraus operators, we show that this type of decoherence does not, in general, lead to th…
Generalized Jaynes-Cummings model as a quantum search algorithm
Alejandro Romanelli
We propose a continuous time quantum search algorithm using a generalization of the Jaynes-Cummings model. In this model the states of the atom are the elements among which the alg…
Non-critical squeezing in 2-transverse-mode optical parametric oscillators
Carlos Navarrete-Benlloch, Alejandro Romanelli, Eugenio Roldán +1
In this article we explore the quantum properties of a degenerate optical parametric oscillator when it is tuned to the first family of transverse modes at the down converted frequ…
