“…Indeed, harnessing high-performance classical error correction codes at extremely low signal reception rates emerged as a pivotal research focus [95], [489]. As a further advance, Liu et al [103] constructed a robust optical fiber based QSDC system successfully operating without active polarization compensation, which also reduced the QBER during eavesdropping detection.…”

Communication security has to evolve to a higher plane in the face of the threat from the massive computing power of the emerging quantum computers. Quantum secure direct communication (QSDC) constitutes a promising branch of quantum communication, which is provably secure and overcomes the threat of quantum computing, whilst conveying secret messages directly via the quantum channel. In this survey, we highlight the motivation and the status of QSDC research with special emphasis on its theoretical basis and experimental verification. We will detail the associated point-to-point communication protocols and show how information is protected and transmitted. Finally, we discuss the open challenges as well as the future trends of QSDC networks, emphasizing again that QSDC is not a pure quantum key distribution (QKD) protocol, but a fully-fledged secure communication scheme.

We propose a protocol to Mentor initiated hierarchical joint remote prepare the arbitrary n-qudit state with generalized Bell states.The agents share generalized Bell states with the Mentor. The Mentor performs five-qudit projective measurements on his entangled particles to initiate the quantum channel shared by the agents. All the senders share the information of the prepared state and make quantum measurements on their particles based on the state to be prepared. The agent in the upper grade needs only the assistance of one of the agents in the lower grade to reconstruct the original state, while the agents in the lower grade need the assistance of all the other agents to recover the original state. It is more convenient in application than others since the agents in the protocol only requires two-particle entanglement for Mentor initiated hierarchical joint remote preparation of an arbitrary n-qudit state.

“…It is a phenomenon in which two or more particles are correlated in such a way that the state of one particle cannot be fully described without considering the other particle.It involves the strange connections highlighted by Einstein, Podolsky, and Rosen (EPR) [1] and utilized by Bell to eliminate explanations of quantum mechanics involving non-local hidden variables [2]. It stands as a fundamental asset in quantum information endeavors such as quantum teleportation [3,4], quantum key distribution (QKD) [5], quantum secure direct communication (QSDC) [6,7], and quantum networks [8]. Measuring entanglement holds significance within quantum information theory.…”

The ease of simulating quantum physics using numerical tools is attributed to the linearity of quantum physics algebra.Conversely, as the size of quantum systems grows, the demand for classical resources in simulation escalates exponentially.Consequently, ensuring sufficient accuracy is crucial for optimizing simulation tool performance. Quantum entanglement,a pivotal phenomenon in quantum information underpinning various communication protocols, quantum algorithms, andcryptography, is profoundly influenced by system size, leading to an exponential increase in the required classical resources asthe quantum system scales up. In this context, IBM’s quantum platforms stand as essential simulation tools for achieving highlyaccurate measurements of entanglement. This article leverages the Qiskit package to delve into the exploration of one suchmeasurement aspect of entanglement, namely, concurrence, within pure two-qubit quantum systems.
