As the research in quantum key distribution (qkd) technology grows larger and becomes more complex, the need for highly accurate and scalable simulation technologies becomes important to assess the practical feasibility and foresee difficulties in the practical implementation of theoretical . Christopher pugh of the department of physics and astronomy is presenting his thesis: free space quantum key distribution to moving platforms christopher is supervised by iqc faculty member thomas jennewein. Quantum key distribution (qkd) is a method to solve this problem using quantum communication it relies on the fact that any attempt of an adversary to wiretap the communication would, by the laws of quantum mechanics, inevitably introduce disturbances which can be detected.
Quantum key distribution (qkd) is a revolutionary security technology that exploits the laws of quantum mechanics to achieve information-theoretic secure key exchange. This thesis explains how the model was developed, validated and presents results from a simulated year-long study of satellite-based quantum key distribution it was . Phase shift quantum key distribution systems thesis, although i will be much closer to some of my friends i will also be far away from some others, and i will .
Abstract: in this thesis, we study two approaches to achieve device-independent quantum key distribution: in the first approach, the adversary can distribute any system to the honest parties that cannot be used to communicate between the three of them, ie, it must be non-signalling.

Physical components modeling in quantum key distribution towards security analysis xilong mao, yan li, yan peng, and baokang zhao , college of computer, national university of defense technology. Quantum key distribution (qkd) is a secure communication method which implements a cryptographic protocol involving components of quantum mechanicsit enables two parties to produce a shared random secret key known only to them, which can then be used to encrypt and decrypt messages. An empirical analysis of the cascade secret key reconciliation protocol for quantum key distribution thesis timothy i calver, captain, usaf afit/gir/env/11-s01. In this thesis, we begin by studying the effect of using an adaptive optics system to improve the efficiency of a free space link to a satellite for quantum key distribution adaptive optics has been used extensively in astronomy and has the potential to increase the average optical intensity received by the satellite.
