Abstract

The entanglement properties of the quantum channel in quantum communication did not play well, in order to realize quantum communication at superluminal speed with the help of this entanglement property, a kind of quantum communication mode which can measure the change of quantum information is proposed in this article. This method can bypass the classical channel part in the quantum communication. In the concrete realization process, by combining the quantum weak measurement method, information transmission can be carried out without destroying entangled states, so as to achieve superluminal communication.

Reversion of weak-measured quantum entanglement state*

Shao-Jiang Du, Yonggang Peng, Hairan Feng +3 more

We theoretically study the reversible process of quantum entanglement state by means of weak measurement and corresponding reversible operation. We present a protocol of the reversion operation in two bodies based on the theory of reversion of single photon and then expend it in quantum communication channels. The theoretical results demonstrate that the protocol does not break the information transmission after a weak measurement and a reversible measurement with the subsequent process in the transmission path. It can reverse the perturbed entanglement intensity evolution to its original state. Under the condition of different weak measurement intensity the protocol can reverse the perturbed quantum entanglement system perfectly. In the process we can get the classical information described by information gain from the quantum system through weak measurement operation. On the other hand, in order to realize complete reversibility, the classical information of the quantum entanglement system must obey a limited range we present in this paper in the reverse process.

Properties of the Quantum Channel

László Gyöngyösi, Sándor Imre

Quantum information processing exploits the quantum nature of information. It offers fundamentally new solutions in the field of computer science and extends the possibilities to a level that cannot be imagined in classical communication systems. For quantum communication channels, many new capacity definitions were developed in comparison to classical counterparts. A quantum channel can be used to realize classical information transmission or to deliver quantum information, such as quantum entanglement. In this paper we overview the properties of the quantum communication channel, the various capacity measures and the fundamental differences between the classical and quantum channels.

Principle and method of faster-than-light quantum communication

Ji-Yuan Gu, Pei Dong, Bao-Guo Dong

Aiming at the challenge of possibility and feasibility of the faster-than-light quantum communication, the principle is based on the microscopic mass-energy systems correlating with spacetime model and the mass-energy spacetime correlation interactions, we present a kind of possible faster-than-light quantum communication mechanism and its feasible working mode, namely via the microscopic mass-energy systems composed of two quantum entanglement particles correlate with spacetime, to solve the mechanism of transmitting its interactions, combine the nonlocality and quantum operability of quantum entanglements, and add the orderly storage working mode of entanglement particle pairs, with the correlating states between entanglement particle pairs correspond and convert into information encoding, namely could realize the long-distance real-time dynamical information exchange, linking-acting and communication, it also can be referred to as the faster-than-light quantum communication. In this communication procedure, to utilize the long-distance real-time dynamical linking-acting effects of quantum entanglement particles, no need of interaction propagators, directly create and carry out interactions, nonuse any carrier of transmitting information, there is no object in existence to need motion at all, naturally no the limit of speed of light also, therefore, such kind of communication mode is feasible in scientific principles, the presented communication method is feasible technologically. Such kind of communication method, no need of the realized conditions and related complicated systems of the information channels and information transmission carriers of common quantum teleportation systems, just can realize the working and operating mode of noninterference at all, unable interception, unable shield, absolute secrecy, faster-than-light, and the long-distance real-time quantum communication and remote control, which also can make its actual application in technology and engineering become feasible. That can be used in the environmental conditions that the existing communication and remote control technology can not apply or difficultly, for example deep stratum, deep sea, deep space, remote mountains, dangerous zone etc. Any other method can not realize the long-distance real-time communication and remote control.
