BB84 with Both Several Cloning and Intercept-resend Attacks

The goal of the protocol QKD BB84 is to allow a transmitter and a receiver which uses a quantum channel to exchange their keys and to detect the presence of eavesdropping attacks. In the present research, we investigate the effect of several eavesdroppers with both intercept-resend and cloning attacks. We will propose the different possible cases of the positioning of the eavesdroppers and their strategies of attacks; also we will calculate the mutual information for each case. The explicit expressions of the mutual information and quantum error clearly show that the security of the exchanged information depends on the numbers of the eavesdroppers and their attacks parameters on the quantum channel

Theoretical and experimental Investigation of Structural, electronic and optical properties of neodymium doped ZnO

The morphological and cathodoluminescent properties of Nd doped zinc oxide thin films deposited by reactive chemical pulverization spray pyrolysis technique on heated glass substrates at 450 °C are being reported. The films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and cathodoluminescent (CL) spectroscopy. We have also used the Generalised Gradient Approximation (GGA)-the Self Interaction Corrected (SIC) to determine Electronic structure and x ray absorption
