Influence of experimental parameters inherent to optical fibers on Quantum Key Distribution, the protocol BB84
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2018, Vol 21, Issue 1
Abstract
In this work, we represent the principle of quantum cryptography (QC) that is based on fundamental laws of quantum physics. QC or Quantum Key Distribution (QKD) uses various protocols to exchange a secret key between two communicating parties. This research paper focuses and examines the quantum key distribution by using the protocol BB84 in the case of encoding on the single-photon polarization and shows the influence of optical components parameters on the quantum key distribution. We also introduce Quantum Bit Error Rate (QBER) to better interpret our results and show its relationship with the intrusion of the eavesdropper called Eve on the optical channel to exploit these vulnerabilities.

Temperature effect on light polarization in uniaxial crystals
It has been shown that changes in temperature of uniaxial single crystal are accompanied by changes in the polarization plane angular position and the light intensity that subsequently passes through the polarizer, uniax...
In–HgCdTe–In structures with symmetric nonlinear I–V characteristics for sub-THz direct detection
This paper reports on the development and investigations of In–Hg1–xCdxTe–In structures with symmetric nonlinear I–V curves that are sensitive to sub-terahertz radiation. It is shown that at low currents photoresponse of...
Structural, electrical and optical investigations of Cu6PS5Br-based thin film deposited by HiTUS technique
Cu6.35P1.77S4.72Br0.15 thin film was obtained using the high target utilization sputtering onto c-cut sapphire substrates. X-ray diffraction studies show the film to be amorphous with some crystalline inclusions. SEM inv...
Using nanosphere lithography for fabrication of a multilayered system of ordered gold nanoparticles
New modification of nanosphere lithography has been realized to obtain multilayered systems of ordered gold nanopartciles (NP). NP have been formed using vacuum deposition of 5…60-nm layer of gold on ionic etched multila...
Influence of Mn doping on ZnO defect-related emission
Defect related emission in undoped and doped with manganese ZnO ceramics was investigated. Mn concentration NMn was varied from 1019 to 1021 cm–3.The samples were sintered for 3 hours in air at 1100 °C. The color of ZnO:...
