The characteristics of quantum channel play important roles on designing a high performance quantum communication system. In this paper, we analyze the fidelity of polarization state travelling through a non-Markovian optical fiber depolarizing quantum channel with color noise environment. The quantum bit error rate (QBER) of a polarization coding BB84 quantum key distribution (QKD) system under non-Markovian...
We analyze the performance of different Passive Optical Network (PON) topologies for the distribution of multiuser quantum keys using subcarrier multiplexing and BB84 protocol in terms of the achievable Quantum Bit Error Rate (QBER) and the useful key distribution rate.
Modern information security systems require use of cryptographic key distribution systems connecting two remote parties. In the present work we propose modified quantum key distribution protocol with time coding and present analysis of practically feasible attacks on this protocol as well as some experimental results, that show the possibility of its successful implementation.Our analysis of security...
A six-user quantum key distribution network implemented on a bus topology is experimentally demonstrated. The network employs the BB84 protocol to transmit cryptographic keys encoded unto the phase states of highly attenuated laser light to distances of up to 31 km in a standard telecommunication-grade fiber. Each user on the network is assigned a unique wavelength for communication with the network...
