In this article, we briefly review the dynamical and thermodynamical aspects of different forms of quantum motors and quantum pumps. We then extend previous results to provide new theoretical tools for a systematic study ...

Promising applications of the anisotropic quantum Rabi model (AQRM) in broad parameter ranges are explored, which is realized with superconducting flux qubits simultaneously driven by two-tone time-dependent magnetic fields. ...

We compare the efficiencies of two interesting schemes to generate truncated states of the light field in running modes, namely the “quantum scissors” and the “beam-splitter array” schemes. The latter is applied to create ...

This thesis presents several quantum circuit implementations of discrete and continuous quantum walks in cycle graphs. Quantum walks have become an important tool for developing quantum algorithms, that is why this work ...

The transmission of quantum states through spin chains is an important element in the implementation of quantum information technologies. Speed and fidelity of transfer are the main objectives which have to be achieved by ...

In this paper we show that the electronic properties of multi-open dots structures are strongly modified by even smalt changes in their geometries. Our discussion of these effects is done in terms of the interaction among ...

We show that a recent proposal for the generation of displaced number states [G.C. de Oliveira et al., Physica A 351 (2005) 251] is misleading and cannot be implemented experimentally. We then discuss the possibility of ...
