Joint remote state preparation (JRSP) of two-qubit equatorial state in quantum noisy channels AbstractThis letter reports the influence of noisy channels on JRSP of two-qubit equatorial state. We present a scheme for JRSP of two-qubit equatorial state. We employ two tripartite GreenbergerHorne-Zeilinger (GHZ) entangled states as the quantum channel linking the parties. We find the success probability to be 1/4. However, this probability can be ameliorated to 3/4 if the state preparers assist by transmitting individual partial information through classical channel to the receiver non-contemporaneously. Afterward, we investigate the effects of five quantum noises: the bit-flip noise, bit-phase flip noise, amplitude-damping noise, phase-damping noise and depolarizing noise on the JRSP process. We obtain the analytical derivation of the fidelities corresponding to each quantum noisy channel, which is a measure of information loss as the qubits are being distributed in these quantum channels. We find that the system loses some of its properties as a consequence of unwanted interactions with environment. For instance, within the domain 0 < λ < 0.65, the information lost via transmission of qubits in amplitude channel is most minimal, while for 0.65 < λ ≤ 1, the information lost in phase flip channel becomes the most minimal. Also, for any given λ, the information transmitted through depolarizing channel has the least chance of success.

“…Now, what will be the effects of noisy channels on JRSP? Only few studies such as [16,17,18,19] have attempted to deal with related problems and to our best knowledge, JRSP of equatorial state under the influence of noise has not been studied till now. It is therefore the priority purpose of this study to examine this.…”

We present a scheme for joint remote state preparation (JRSP) of three-particle state via three tripartite Greenberger-Horne-Zeilinger (GHZ) entangled states as the quantum channel linking the parties. We use eight-qubit mutually orthogonal basis vector as measurement point of departure. The likelihood of success for this scheme has been found to be 1/8. However, by putting some special cases into consideration, the chances can be ameliorated to 1/4 and 1. The effects of amplitude-damping noise, phase-damping noise and depolarizing noise on this scheme have been scrutinized and the analytical derivations of fidelities for the quantum noisy channels have been presented. We found that for 0.55 ≤ η ≤ 1, the states conveyed through depolarizing channel lose more information than phase-damping channel while the information loss through amplitude damping channel is most minimal. Keywords IntroductionWhen a pair of particles is generated such that the quantum state of each particle cannot be elucidated independently, we referred to them as being entangled. One of the effortless ways to create entanglement is using a very powerful laser along with some very special crystals in order to entangle pair of photons which are the smallest unit of light. Experimental realization of quantum entanglement has been achieved and presented more elaborately in reference [1]. Quantum entanglement represents basic ingredient in quantum information processing.

Entanglement has been found resourceful in quantum state sharing [2]. Information stored in quantum system can be teleported from one location to the other with the aid of shared entangled state [3]. Some other processes that exploit quantum entanglement include quantum dense coding [4], quantum secure direct communication [5] and remote state preparation (RSP) [6].The quantum teleportation can be described as a process by which quantum information is being transmitted from one location to another, with the aid of classical communication and erstwhile shared quantum entanglement between the sending and receiving location. In quantum teleportation, the sender has a particle of unknown state. Whereas, in RSP, the sender does not own the particle

Information security protection is always one of very significant and fundamental issues in edge computing, generally including cryptography, authentication, intrusion detection, privacy protection, and other technologies, and so forth.Quantum authentication is one of the latest extensions of authentication technology in quantum field. So far, most of the quantum identity authentication protocols proposed are based on noise-free environments. However, due to the existence of quantum noise in quantum channels is inevitable, the noise immunity is very important to quantum identity authentication. In this article, a novel quantum identity authentication protocol based on three-photon error avoidance code is proposed. In this protocol, quantum information is encoded on the noiseless subsystem, so the protocol can effectively resist on the interference of noise in the quantum channel to information transmission. The comprehensive analysis of antinoise performance and the security analysis on various eavesdropping attacks shows that the new protocol proposed in this article has not only good antinoise performance but also good security. INTRODUCTIONEdge computing is a distributed computing paradigm, which can make computing and storage closer to the actual user needs, so as to improve demand response speed and reduce the bandwidth requirements of information transmission. 1,2 The distributed feature of this mode requires not only encryption of data but also other different information security protection mechanisms 3-5 because data may be transmitted between different distributed nodes connected through the Internet before it finally reaches the cloud. [6][7][8] As a result, information security protection becomes one of the very significant and fundamental issues in edge computing, 9,10 which generally includes cryptography, 11 authentication, intrusion detection, and privacy protection. 5,[12][13][14] Authentication can encrypt and decrypt the information transmitted on the network, realize digital signature and signature verification, and ensure the security and integrity of the information transmitted on the network. 4,15 Quantum authentication is one of the latest and most advanced authentication technologies in information security. 11,14,15 At present, quantum authentication can be mainly divided into three aspects: quantum identity authentication, quantum channel authentication, and quantum message authentication. This article is about to discuss the quantum identity authentication.Abbreviations: ANA, antinuclear antibodies; APC, antigen-presenting cells; IRF, interferon regulatory factor.
