Bidirectional Transmission

In this paper, we give a further discussion of short-distance teleportation. We propose bidirectional, rotation and cyclic rotation teleportation schemes for short-distance participants, respectively. In our bidirectional transmission scheme, the quantum channel is still an EPR pair and an auxiliary qubit in the ground state [Formula: see text], and two participants can transmit an unknown single-qubit state to each other. In the rotation and cyclic rotation schemes, bidirectional transmission is performed between two adjacent participants in turn. The unknown state qubits of the participants collapse into the ground state after one bidirectional transmission, and can be used as auxiliary qubits in subsequent bidirectional transmission. After a complete state rotation, each participant has held the unknown state of the other participants, and the last one owned by the participant is still the original unknown state. Although the schemes we proposed are applicable to a small range of transmission, they have certain advantages in saving quantum resources.

Bidirectional Transmission

This paper presents a scheme of information transmission system for undersea observation platform based on all-optical network. Through flexible using of WDM, OADM, EDFA, RFA, DCF and other technology, it effectively compensates chromatic dispersion, restrains nonlinear effects and noise problems. Fibers in primary nodes are directly assigned to ensure mutual independence between different transmission links. Dual-fiber bidirectional transmission mode that wavelength of one fiber drops to the node by OADM, then return to the same transmission station in the other fiber, increases the reliability of the transmission system. The simulation results show that this scheme can ensure information transmission quality and effectively achieve wavelength adding and dropping, further verify the feasibility of the scheme.
