Simulation of Quantum Channel and Analysis of Its State Under Network Disruption

Abstract Presently the work done in the field of quantum cryptography is pri-
marily theoretical, the purpose of this paper is to showcase its implementation in an

observable manner. Thus, this paper establishes a more secure network using
quantum key distribution (QKD) for data transfer between sender and receiver and
also enables the quick identification of an eavesdropper in the said network. Ananalysis of the quantum channel traffic at the ideal state and also during network
disruption (i.e. when the quantum state collapses) has been carried out. Due to thecomplex nature of quantum networks, a physical implementation of the same is notfeasible. Hence, a simulation has been implemented via the use of NS-3 (Network
Simulator Version 3).
