Abstract

Signaling is an essential and important component in quantum communication. However, the current research on the quantum signaling transmission computing model has not yet commenced. In this paper, based on the background of noise, the transmission damage probability model of quantum signaling is presented. The relationship between the fidelity of signaling and the samples sent is studied. The simulation results show that, when the state of quantum entanglement is the maximum state of entanglement, the fidelity is 1. The fidelity is increased with the number of samples and limited to 1. For the signaling standards of the future quantum communication system, this study has good technical support role.

Transmission fidelity analysis of multiuser quantum signaling under noisy background

Min Nie

To research the problem of transmission fidelity of multiuser quantum signaling under noisy background,the definition and transmission method of signaling fidelity were presented.The relationship between entanglement degree and signaling successful transmission ratio was analyzed.The computing model of quantum entanglement signaling was put forward,and the simulation for signaling transmission fidelity was achieved finally.The results show that the interference of environment noise to quantum signaling channel entanglement degree restricts the distance and efficiency of the signaling transmission.And the signaling fidelity is convergence gradually with the increase of the sample's number.To insure entanglement signaling transmission precision,the sample's number should be adjusted properly according to the communication distance.

Poisson survival model of quantum entanglement signaling network and fidelity analysis

Min Nie, Zhang Lin, Liu Xiaohui

Quantum signaling states have decoherence because of the environment during the transmission. It causes signaling damage and thus will have impact on building high survivability quantum entanglement signaling network. In order to study the influence deeply, Poisson damage model of quantum signaling network is established. First, disaster magnitude is defined base on signaling fidelity. Second, average damage signaling quantum bits and survival function of quantum signaling network is put forward by basic quantum theory. At last, research on the signaling damage repair strategy and simulation is analyzed. Simulation results show that increasing of disaster magnitude will greatly reduce the signaling network survivability. However, increasing the nodes and controlling signaling damage caps may improve survivability. The repair strategy which costs small number of cycles can rapidly increase the signaling fidelity from 0.6 to 0.9 and the survival function of the signaling network from 0.4 to 0.9.

Probability model of quantum signaling transmission damage and repair strategy

Changxing Pei

A quantum signaling transmission scheme based on quantum entanglement,local unitary operation and teleportation is proposed for signaling transmission in a multiuser quantum signaling network with multi-stage hierarchy level network topology.The analytical result shows that the scheme is secure in case of eavesdropping attack including intercept-measure-resend attacks,intercept-replace and adding-ancilla attacks.Consequently,the probability model of quantum signaling transmission damage probability and the repair strategy of the damage of quantum signaling are presented,and the probability model in noise background and non-ideal traditional channel has very low complexity.

A model of quantum signaling repeater and its parameters simulation

Xue Le, Min Nie, Xiaohui Liu

In order to solve the damage problem during remote transmission of quantum signaling, a repeater model of signaling quantum is proposed. In this model, firstly purifying and distributing entanglement of the received signaling quantum state is carried out, to establish entangled channels between the signed sending and receiving. Secondly, through quantum entanglement swapping the quantum signaling is transmitted, for completing the quantum signaling relay. Simulation results show that the success rate of signaling relay can reach more than 97% under the condition that the fidelity is 0.98 and the entangled pairs successful establishing rate is 0.98; the throughput of quantum signaling relay is up to 183kbps when the probability of entanglement swapping, purification, and entangled pairs successful establishing is 0.98.

Technical Analysis of Quantum Signal Performance in the Framework of Practical Experiments

Mariam Janelidze, Lasha Janelidze

The rapid development of the digital era and the increasing demands of information technologies create a need to create more reliable, secure and efficient communication systems. In this context, quantum signals represent a technology of the future that responds to the challenges that classical signal systems can no longer cope with — for example, the highest level of information security, accuracy and transmission speed. The use of quantum entanglement, superposition and correlations makes it possible to protect and process information at the highest level. Accordingly, the implementation of quantum signals is critically important for areas such as quantum communication, secure cyberinfrastructure, high-tech sensors and quantum computing systems. The paper reviews the role of quantum signals in modern technologies and their potential in the near future. Quantum signal theory combines the principles of quantum physics, information theory and signal processing. These features provide the highest accuracy in information transmission and processing, which is especially important in the development of quantum communication, quantum radars, and quantum sensors. This paper reviews the theoretical foundations of quantum signals, basic models, and their potential applications in modern technologies.
