Based on the classical time division multi-channel communication theory, we present the scheme of quantum channel-time division multiplex (QC-TDM). Moreover, the model of quantum time division multiplexer (QTDM) are proposed. The quantum bit error rate (QBER) is analyzed and the QBER simulation test is performed. The scheme shows that the QTDM can carry out multi-user communication through quantum...
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.
This paper provides an analysis of the performance of different passive optical network (PON) topologies for the distribution of multiuser quantum keys using subcarrier multiplexing and the Bennet-Brassard (BB84) protocol. PON topologies are evaluated in terms of the achievable quantum bit error rate (QBER) and the useful key rate. Results show that wavelength routed (WR) networks outperform broadcast...
