Abstract

This paper explores the fundamental aspects and protocols of quantum dense coding and teleportation, which are essential for secure quantum information transfer. We demonstrate the robustness of these protocols against traditional forms of attack. To establish these findings, we delve into the core principles of quantum mechanics, including quantum measurements, entanglement, qubits, and both single and multi-qubit operations, with an emphasis on CNOT gates. Additionally, we delineate the requisite conditions for participants in these quantum protocols.

Quantum Teleportation

Bennett and his team pioneered the quantum teleportation protocol, a breakthrough where Alice transmits quantum information to Bob through a pre-shared entangled quantum channel. Remarkably, this transmission occurs without physically moving the information, relying on a combination of classical communication and quantum entanglement. This protocol not only demonstrates the essence of quantum entanglement but also underscores its potential in the realm of information transfer. The success of quantum teleportation experiments extends across various physical systems, with a particular emphasis on achieving effectiveness over long distances. Looking forward, future developments in this field may lead to multi-party protocols, thereby advancing both quantum communication and computing capabilities. A crucial component in quantum teleportation networks is controlled quantum teleportation (CQT), holding significant promise for the emerging concept of the quantum internet. In the preceding chapter, our exploration centered on the practical application of quantum teleportation protocols, with a specific focus on two key approaches: standard quantum teleportation and CQT. Our examination delved into the fundamental principles of quantum teleportation, encompassing critical concepts such as quantum entanglement, non-cloning, superposition, and the importance of measurements like fidelity. Throughout the chapter, we dedicated special attention to both the theoretical and experimental aspects of quantum teleportation, considering the intricacies of systems with continuous variables (CVs) as well as those with discrete variables (DVs).

Controlled remote implementation of operations for many systems

Chengxu Liu

Quantum communication plays a key role in the next generation of information transfer and security schemes, by using quantum entanglement and measurements from quantum mechanics. We introduce the mathematical and physical foundations of quantum communication, such as the CNOT gate and Kronecker product. Then we propose two quantum communication protocols, namely dense coding and stealth coding. These protocols offer unique advantages that are theoretically unbreakable. Then we extend the protocols to the quantum communication protocol allowing for third-party supervision to ensure information security. Based on this, a communication protocol involving four parties is designed, enabling them to exchange information while being supervised.

Perfect quantum teleportation and dense coding protocols via the 2N-qubit W state

Mei-Yu Wang, Fengli Yan

In this paper, we investigate perfect quantum teleportation and dense coding by using an 2 N -qubit W state channel. In the quantum teleportation scheme, an unknown N -qubit entangled state can be perfectly teleported. One ebit of entanglement and two bits of classical communication are consumed in the teleportation process, just like when using the Bell state channel. While N + 1 bits of classical information can be transmitted by only sending N particles in the dense coding protocol.

Quantum communication protocols: From theory to implementation in the quantum computer

Abdallah Slaoui, Nada Ikken, L.B. Drissi +1 more

In recent years, notable progress has been achieved in the theoretical investigation of quantum systems as computational tools. This has given rise to the development of quantum computing and quantum information, fields that delve into the feasibility of employing quantum systems for information processing objectives. Essential to the manipulation of qubits and the facilitation of quantum computations are quantum gates. Comparable to classical gates, these quantum counterparts are actions designed to alter the state of qubits. Among them are the Hadamard gate, CNOT gate, and Toffoli gate, each imbued with distinct functionalities that collectively enrich the repertoire of quantum computation tools. As we progress through this chapter, we embark on a journey that unveils the complexities of quantum communication. From the foundational concepts of quantum mechanics to the advanced realms of quantum teleportation, we have witnessed the potency of quantum entanglement to teleport quantum states. Furthermore, we have delved into the practical implementation of circuits using Qiskit, gaining a grasp of the art of orchestrating qubit operations, measurements, and corrections. Standing at the convergence of the quantum and classical realms, this chapter aims to provide a comprehensive perspective, exposing the intricate web of quantum communication and computing, while paving the way for a future in which quantum technologies redefine the boundaries of the achievable.

Quantum Communication Protocol Design Based on Quantum Mechanics Principles

Jincheng Zhang

This paper proposes a novel communication protocol design leveraging the principles of quantum mechanics, specifically quantum entanglement and quantum teleportation. The core claim is to enhance communication security, rate, and reliability by utilizing these quantum phenomena. The protocol is based on Quantum Key Distribution (QKD) protocols, employing entangled particles to securely share cryptographic keys. Furthermore, it incorporates aspects of quantum teleportation to facilitate information transfer. The proposed system fundamentally departs from traditional communication protocols which are vulnerable to eavesdropping, offering a significantly higher level of security due to the inherent properties of quantum mechanics. This design addresses the limitations of classical communication methods and presents a pathway toward truly secure and high-performance communication systems. The key components of this protocol are detailed, including the entanglement generation and distribution, the key exchange process, and the information teleportation scheme. The mathematical framework underpinning these processes is presented, focusing on the core concepts of quantum information theory. ---
