In this work we obtain the electronic states for a semiconductor quantum cylindrical shell in the matrix GaAs Al Ga As 0.35 0.65 . We have assumed that the system has only one band which splits into a sub-bands system due to confinement. We use the formal... see more

The subject of research in the article is the energy spectrum of a multilayer quantum sized structure with an energy profile of a complex shape. The goal of this work is to study the interaction of quantum-confined and quasi- continuum energy states of pa... see more

In a class on quantum mechanics in 1964 at LSU a question was asked whether the potential energies of a multibody could be added up to give the energy state. It was stated that Vanagas was somewhat successful in using 2 body states. In 1971 two hypotheses... see more

: In this paper, we investigated the entanglement properties of the charge-pair cat states based on the linear entropy function. We used these states for the teleportation of a coherent state in two different measurements at the sender by using joint meas... see more

We develop priors for Bayes estimation of quantum states that provide minimax state estimation. The relative entropy from the true density operator to a predictive density operator is adopted as a loss function. The proposed prior maximizes the conditiona... see more

We propose a schematic setup of quantum key distribution (QKD) with an improved secret key rate based on high-dimensional quantum states. Two degrees-of-freedom of a single photon, orbital angular momentum modes, and multi-path modes, are used to encode s... see more

We develop a useful model considering an atom-field system interaction in the framework of pseudoharmonic oscillators. We examine qualitatively the different physical quantities for a two-level atom (TLA) system interacting with a quantized coherent field... see more

Quantum information geometry studies families of quantum states by means of differential geometry. A new approach is followed with the intention to facilitate the introduction of a more general theory in subsequent work. To this purpose, the emphasis is s... see more

The article contains observation on the formation of electron compounds of structural composite materials of the new technology. Investigated in copper-zinc influence of quantum states density on the formation of the phase structure and mechanical propert... see more
