Quantum Internet: key technologies and future prospect by Zishan LIU, Junsen LAI, Wenyu ZHAO

“…The quantum Internet integrates quantum computing, quantum measurement and communication, which can be described as the future goal of the evolution of quantum information technology.However, due to the restrictions of the laws of quantum mechanics, such as quantum teleportation, quantum entanglement, quantum measurement and non-cloning, which all pose new challenges to the quantum networking design.The basic concepts and development paths of the quantum Internet were firstly introduced, and the implementation differences between the classical network and the quantum network were explained.Considering the difference between quantum communication and the traditional communication, the key technologies for realizing the quantum Internet including the quantum physical devices, networking protocol, quantum decoherence and quantum relay were introduced, and finally the prospect and suggestions for developing quantum Internet was presented.…”

Electro-gravity entanglement by Moreno Jose C.

“…One fundamental question is the connection between electrical and gravitational forces. We present a quantum entanglement model, with multiple discrete electrically charged wave-packets, that simulates gravitational attraction among them, where quantum states can have only two wave-packets with opposite charge polarities, with equal absolute values, while the rest remain neutral, relating those charges to gravitational masses. …”

Entanglement negativity and replica symmetry breaking in general holographic states by Xi Dong, Jonah Kudler-Flam, Pratik Rath

“…Abstract The entanglement negativity E $$ \mathcal{E} $$ (A : B) is a useful measure of quantum entanglement in bipartite mixed states. In random tensor networks (RTNs), which are related to fixed-area states, it was found in ref. [1] that the dominant saddles computing the even Rényi negativity E 2 k $$ {\mathcal{E}}^{(2k)} $$ generically break the ℤ 2k replica symmetry. …”

Entangled state testing in the quantum Byzantine agreement by Xia WU, Heng-yue JIA, Jian-ming ZHU

“…In distributed computing,Byzantine agreement is a practical method to solve its fault-tolerance problem.There is a variation of the Byzantine agreement which is called detectable Byzantine agreement.This kind of protocol is unsolvable by classical means,but can be solved using quantum resources——quantum entangled states.A typical quantum detectable Byzantine agreement is the GBKCW protocol.The part with the generation and distribution of the lists in the GBKCW protocol was dealed with.In order to keep the GBKCW protocol from the intercept-and-resend strategy,the property of the determination of entangled states were employed to test the sharing state between the parties.…”
