Abstract

The paper proposes resource and duration evaluations for quantum secure communication (QSC) protocols. In terms of both evaluations, two QSC protocols - two-step quantum secure direct communication (QSDC) protocol and quantum channel compression (QCC)-based QSDC protocol, are compared. It is verified that the QCC-QSDC protocol excels the two-step QSDC in terms of duration, and utilizes slightly less resources for its implementation.

Proposal of Optimality Evaluation for Quantum Secure Communication Protocols by Taking the Average of the Main Protocol Parameters: Efficiency, Security and Practicality

Georgi Bebrov, Rozalina Dimova

In the field of quantum secure communication, there is no evaluation that characterizes quantum secure communication (QSC) protocols in a complete, general manner. The current paper addresses the problem concerning the lack of such an evaluation for QSC protocols by introducing an optimality evaluation, which is expressed as the average over the three main parameters of QSC protocols: efficiency, security, and practicality. For the efficiency evaluation, the common expression of this parameter is used, which incorporates all the classical and quantum resources (bits and qubits) utilized for transferring a certain amount of information (bits) in a secure manner. By using criteria approach whether or not certain criteria are met, an expression for the practicality evaluation is presented, which accounts for the complexity of the QSC practical realization. Based on the error rates that the common quantum attacks (Measurement and resend, Intercept and resend, probe attack, and entanglement swapping attack) induce, the security evaluation for a QSC protocol is proposed as the minimum function taken over the error rates of the mentioned quantum attacks. For the sake of clarity, an example is presented in order to show how the optimality is calculated.

Advances in quantum secure direct communication

Piotr Zawadzki

Abstract The practical implementation of quantum secure direct communication (QSDC) will undoubtedly be a milestone in the development of quantum cryptography. Research is in its final phase and focuses on developing secure protocols that consider realistic constraints and are feasible within the current state of technology. Three well‐known protocols ae compared, Ping‐Pong, Two‐Step and Deng‐Long, in the context of the level of security offered and the challenges related to their implementation. This work explains how the evolution of QSDC protocols from a purely quantum formulation to hybrid classical‐quantum solutions based on the Wyner wiretap channel model can solve most problems encountered. The work aims to inform scientists in other fields of quantum information processing about the latest advances in QSDC. The attached appendix introduces basic concepts for readers unfamiliar with this research area.

QSDC: Future of Quantum Communication A Study

Baldeep Singh Dhillon, Manisha J. Nene

Quantum Secure Direct Communication (QSDC) is a distinctive protocol of quantum communication. It communicates confidential message straight through a quantum channel without a requirement of secret key and cipher-text. It is not solely useful in preventing eavesdropping throughout transmission, but additionally removes the security flaw related with storing and managing the key. Therefore, this protocol of secure communication is different from its typical equivalents and other quantum protocols. In this article, we will bring out the facts that how QSDC is different and better than other protocols of Quantum Communication. The transient details of all the protocols of Quantum communication are studied rigorously and compared with QSDC to demonstrate how QSDC is capable of overcoming the loopholes/shortcomings of alternative protocols. In this paper, protocols of QSDC to mitigate the possible threats available in practical QSDC are discussed and one of the protocol Measurement Device Independent QSDC is demonstrated along with the efficacy of results verified using quantum simulator and quantum machine. The results demonstrate its potential over other protocols of quantum communication and contribution towards empowering secure communication. With the benefits of QSDC over other protocols, it helps as mitigating technique for the possible threats available in other protocols of Quantum communication.

Two-step quantum secure direct communication scheme with frequency coding

Xueliang Zhao, Junlin Li, Peng-Hao Niu +2 more

Quantum secure direct communication (QSDC) is an important branch of quantum cryptography. It can transmit secret information directly without establishing a key first, unlike quantum key distribution which requires this precursory event. Here we propose a QSDC scheme by applying the frequency coding technique to the two-step QSDC protocol, which enables the two-step QSDC protocol to work in a noisy environment. We have numerically simulated the performance of the protocol in a noisy channel, and the results show that the scheme is indeed robust against channel noise and loss. We also give an estimate of the channel noise upper bound.
