In order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. To do this we have investigated optical waveguide both with and without optical pumping. The rate of absorption and emission using an array of AlGaAs/GaAs quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. By con...

The state of a quantum system is not an observable. Given a large number of copies of the system of interest we can obtain a good estimation of the state [1], but it is not possible to determine the state given only a single copy.1 Fundamentally, we can understand this limitation as a manifestation of complementarity, that is, the existence of incompatible observables. It is this limitation, mo...

the aim of this study was to investigate the relationship betweenunderstanding and application of quantum skills in sports organizations. thestudy method was descriptive. the statistical population consisted ofmanagers of the ministry of sport and youth and the heads of selected sportsfederations (n=59). the data were analyzed by descriptive and inferentialstatistics. for data analysis, spearma...

in this work, some of the lattice plasmon quantum features are examined. Initially, the interaction of the far-field photonic mode and the nanoparticle plasmon mode is investigated. We probe the optical properties of the array plasmon that are dramatically affected by the array geometry. It is notable to mention that the original goal of this work is to examine the quantum feature of the array ...

Quantum correlation of two-photon states is utilized to suppress the environmental noise in imaging down single-photon level. However, size coherence area photon pairs limits applications quantum based on spatial correlations. Here, a scheme exploiting twisted with tunable spatial-correlation regions circumvent this limitation proposed. A bulk-density coincidence employed enhance signal. Specif...

In this paper, by using a quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, we present the corrected plasmon dispersion relation for graphene which includes a k quantum term arising from the collective electron density wave interference effects (which  is integer and constant and k is wave vector). The longitudinal ...

Geometric phases in quantum mechanics play an extraordinary role in broadening our understanding of fundamental significance of geometry in nature. One of the best known examples is the Berry phase [M.V. Berry (1984), Proc. Royal. Soc. London A, 392:45], which naturally emerges in quantum adiabatic evolution. So far the applicability and measurements of the Berry phase were mostly limited to sy...

We have developed an enhanced technique for characterizing quantum optical processes based on probing unknown quantum processes only with coherent states. Our method substantially improves the original proposal (Lobino et al 2008 Science 322 563), which uses a filtered Glauber–Sudarshan decomposition to determine the effect of the process on an arbitrary state. We introduce a new relation betwe...
