However, efficient production of maximally entangled states is still a challenge for further progress in quantum computing and quantum communication. In the search for optimal sources of entanglement, quantum dots have emerged as promising candidates, but the presence of dephasing in the generated entangled states raises questions about their real usefulness in large-scale quantum networks. In this work, we evaluate the effects of the exciton fine structure splitting, present in most quantum dot samples, on the fidelity of the BBM92 protocol for quantum key distribution. We find that the protocol’s performance is heavily impacted by such splitting and establish an upper limit for the product between the energy splitting and the exciton lifetime to have a dependable distri...

We found emission spectra for both cases, with and without phonons, whose comparison allows to determine the dissipative effects. On the basis of the obtained results we propose efficient control of the resonance fluorescence of an artificial molecule, suitable for optoelectronic applications.

We calculate the field enhancement factor for nanospheres of various radii by using optical constants obtained from both classical and quantum approaches, and compare their size dependent features. To evaluate the scattered near field, we solve the electromagnetic wave equation within a finite element framework. When quantization of electronic states is considered for the input optical functions, a significant blue-shift in the resonance of the enhanced field is observed, in contrast to the case in which functions obtained classically are used. Furthermore, a noticeable underestimation of the field amplification is found in the calculation based on a classical dielectric function. Our results are in good agreement with available experimental reports and provide relevant information on the cross-over between classical and quantum regime, useful in potentiating nanoplasmonics applications.

An important and sufficient condition for achieving Bloch oscillations is the variation of the depth of the fluid. This variation produces changes in the refraction index and in the wave number of the disturbance in such a way that those changes exhibit discontinuities whose magnitudes are directly associated to the predicted frequency. A dispersion relation, that allows us to obtain the oscillations of the disturbance, is determined and applied. The calculation for stationary waves with such relation shows some indications suggesting oscillations which are a reproduction in the space domain of the Bloch oscillations for electrons under an electric field.

By using both perturbative and polaron approaches, we investigate the influence of carrier-phonon interactions on the emission properties of a two-level solid-state emitter, simultaneously coupled to two intense distinguishable lasers. Phonon decoherence effects on the emission spectra are found modest up to neon boiling temperatures (∼ 30 K), as compared with photon generation at the Fourier transform limit obtained in absence of lattice vibrations (zero temperature). These results show that optical switching and photonic modulation by means of double dressing, do not require ultra low temperatures for implementation, thus boosting its potential technological applications.
Semiconductor quantum dot/rod/emitter upconverter nanostructures are promising for photovoltaic a... more Semiconductor quantum dot/rod/emitter upconverter nanostructures are promising for photovoltaic applications due to their broadband absorption and tunability. However, the best reported upconversion quantum yield is only 2%, limited by competing carrier relaxation mechanisms. In this work, both steady-state and excitation wavelength-dependent time-resolved photoluminescence are used to measure carrier separation and transfer dynamics as a function of nanostructure morphology. We synthesize and measure core-only, core/rod intermediates, and full core/rod/emitter structures and perform three-dimensional (3D) modeling of the electron and hole wavefunctions for each of these structures. We observe that addition of the rod to the core quantum dot improves passivation and carrier separation. An increase in core homogeneity and rod alloying are both found to result in higher radiative recombination rates relative to nonradiative recombination, in agreement with an increase in upconversion efficiency, as previously reported by the authors. Collectively, these results illustrate how the nanostructure morphology and composition influence carrier separation and recombination, suggesting a path toward improved upconversion performance.

Within the density operator formalism, we derive a variational master equation valid for broader ranges of temperatures, pumping rates, and radiation-matter couplings, than previous studies. From the obtained master equation, fluorescence spectra for various thermal and exciting conditions are numerically calculated, and compared to those computed from weak coupling and polaronic master equations, respectively. Our results evidence the breakdown of those rougher approaches under increased temperature and strong pumping.

In the framework of the effective mass approximation, first-order scattering rates for interaction between confined electron-"free" electron and electron-longitudinal acoustic phonon at room temperature are calculated in the high tunneling regime, and used to evaluate the dynamics of the population and coherence in the first three confined levels under a short ac electric field pulse. Small values of these rates dependent upon the bias field make feasible the emission of coherent radiation at terahertz range.

As a main result, for strongly coupled dots we predict substantial reduction of optical fine structure splitting without any drop in the optical oscillator strength. This special reduction diminishes the distinguibility of polarized decay paths in cascade emission processes suggesting the use of stacked quantum dot molecules as entangled photon-pair sources.

By numerically obtaining dielectric functions from different sets of eigenenergies and eigenstates, we simulate the absorption spectrum and the field enhancement factor for nanoparticles of various sizes, within a quantum framework for both infinite and finite potentials. The simulations show significant dependence on the sphere radius of the dipolar surface plasmon resonance, as a direct consequence of energy discretization associated to the strong confinement experienced by conduction electrons in small nanospheres. Considerable reliance of the calculated optical features on the chosen wave functions and transition energies is evidenced, so that discrepancies in the plasmon resonance frequencies obtained with the three studied models reach up to above 30%. Our results are in agreement with reported measurements and shade light on the puzzling shift of the plasmon resonance in metallic nanospheres.

Status Solidi B 246, 2257 (2009)] on electric field effects and nonlinear optical properties of excitons confined in spherical quantum dots. We find an inconsistency in the calculation of the dipole moments, which lead to vanishing nonlinear optical results. For the same set of parameters studied by Xie, we obtain new and reliable optical rectification coefficients via a finite element approach.

By using a full configuration interaction method as reference, we compare two different ways to obtain the eigenvalues of the system by finite element simulations, one of which approximately separates the Coulomb interaction and averages the longitudinal part. We find that in the regime of low aspect ratios, the results from the approximate scheme with approximation are quite optimal (< 0.05% of difference respect to the reference), but once the dots turn more and more thicker, the results become just acceptable (> 0.5% of difference), due to underestimation of the Coulomb interaction. On the other hand, for the nonapproximated finite element approach the results are consistently reliable along the different field and aspect ratio regimes (< 0.02% of difference respect to the reference). This allows us to present a novel, efficient and highly accurate method for obtaining electronic structure of interacting particles in 0D nanostructures.

Electronic structure is obtained by finite element calculations, and Coulomb effects are included using a perturbative approach. According to our simulated spectra, bright excited states may become optically accessible at low temperatures in hybridization regimes where intermixing with the ground state is achieved. Our results show effective magnetic control on the energy, polarization and intensity of emitted light, and suggest these coupled nanostructures as relevant candidates for implementation of quantum optoelectronic devices.

The mag-nitude of the coupling between pairs is calculated as function of the distance between dots and it is compared with the bandwidth in chains. It was found that the nearest neighbor approximation is enough to take into account the magnitude of the coupling in this kind of systems. It was also ob-served that the spherical geometry helps more than the cubic one the formation of Wannier ladders under external bias.

También se observó que la geometría esférica es más favo-rable que la cúbica para la formación de escaleras de Wannier bajo la acción de campos eléctricos dc externos.
