  1. Entanglement-Assisted Communication of Classical and Quantum Information

    Min-Hsiu Hsieh, Mark M. Wilde · 2010 · IEEE Transactions on Information Theory · 111 citations

    In this paper, we consider the problem of transmitting classical and quantum information reliably over an entanglement-assisted quantum (EAQ) channel. Our main result is a capacity theorem that gives a 3-D achievable rate region. Points in the region are rate triples, consisting of the classical communication rate, the quantum communication rate, and the entanglement consumption rate of a particular coding scheme. The crucial protocol in achieving the boundary points of the capacity region is a protocol that we name the classically enhanced father(CEF) protocol. The CEF protocol is more general than other protocols in the family tree of quantum Shannon theoretic protocols, in the sense that

  3. Photonic entanglement for fundamental tests and quantum communication

    Wolfgang Tittel, Gregor Weihs · 2001 · Quantum Information and Computation · 63 citations

    Entanglement is at the heart of fundamental tests of quantum mechanics like tests of Bell-inequalities and, as discovered lately, of quantum computation and communication. Their technological advance made entangled photons play an outstanding role in entanglement physics. We give a generalized concept of qubit entanglement and review the state of the art of photonics experiments.

  5. MULTIPARTITE ENTANGLEMENT UNDER STOCHASTIC LOCAL OPERATIONS AND CLASSICAL COMMUNICATION

    AKIMASA MIYAKE · 2004 · International Journal of Quantum Information · 24 citations

    Stochastic local operations and classical communication (SLOCC), also called local filtering operations, are a convenient, useful set of quantum operations in grasping essential properties of entanglement. We give a quick overview of the characteristics of multipartite entanglement in terms of SLOCC, illustrating the 2-qubit and the rest (2×2×n) quantum system. This not only includes celebrated results of 3-qubit pure states, but also has implications to 2-qubit mixed states.

  6. Balance of information in bipartite quantum-communication systems: Entanglement-energy analogy

    Ryszard Horodecki, Michał Horodecki, Paweł Horodecki · 2001 · Physical Review A · 23 citations

    We adopt the view that information is the primary physical entity possessing objective meaning. Based on two postulates stating that (i) entanglement is a form of quantum information corresponding to internal energy and (ii) sending qubits corresponds to work, we show that in the closed bipartite quantum-communication systems, the information is conserved. We also discuss the entanglement-energy analogy in the context of the Gibbs-Helmholtz-like equation connecting the entanglement, of formation, distillable entanglement, and bound entanglement. Then we show that in the deterministic protocols of distillation, the information is conserved. We also discuss the objectivity of quantum informati

  8. An analysis of concurrence entanglement measure and quantum fisher information of quantum communication networks of two-qubits

    Volkan Erol, Sinan Bugu, Fatih Özaydin, et al. · 2014 · Signal Processing and Communications Applications Conference (SIU) · 13 citations

    Quantum entanglement is one of key concepts in quantum communication engineering. Ordering the quantum systems according to their entanglement measures is a popular problem of the field. For two level (qubit) systems of two particles, state ordering has been studied with respect to well-known entanglement measures such as Concurrence, Negativity and Relative Entropy of Entanglement (REE) [1-5]. In this work, we study the state ordering of the two-qubit systems with respect to Quantum Fisher Information vs. Concurrence. In particular, constructing 1K random states and calculating their Concurrences and Negativities, we obtain the orderings of the states by comparing these results with Quantum

  11. Age of Information for Quantum Communication Channels with Monogamy of Entanglement

    Aygun Jabrayilova, Elena Camuffo, Laura Crosara, et al. · 2025 · IEEE International Mediterranean Conference on Communications and Networking (MeditCom) · 3 citations

    For time-critical applications, the freshness of information often goes hand in hand with confidentiality to ensure the integrity of sensitive data. Quantum communications are expected to provide secure exchanges of information thanks to the principles of quantum mechanics, such as entanglement, to protect against data breaches. In this paper, we analyze an information update system, where communication between a sender and receiver occurs through a quantum channel, and we consider the presence of two malicious eavesdroppers. Quantum communications already allow consent to identify compromised data, but we show that the presence of multiple eavesdroppers is even more thwarted by a property o

  13. Hybrid entanglement for quantum information and communication applications

    Isaac M. Nape, Bienvenu I. Ndagano, Benjamin Perez-García, et al. · 2017 · 1 citations

    Combining the multiple degrees of freedom of photons has become topical in quantum communication and information processes. This provides advantages such as increasing the amount of information that is be packed into a photon or probing the wave-particle nature of light through path-polarisation entanglement. Here we present two experiments that show the advantages of using hybrid entanglement between orbital angular moment (OAM) and polarisation. Firstly, we present results where high dimensional quantum key distribution is demonstrated with spatial modes that have non-separable polarisation-OAM DOF called vector modes. Secondly, we show that through OAM-polarisation entanglement, the tradi

  19. Title: Quantum Decoherence as a Tool for Information Transfer – Exploiting Entanglement for Secure Communication

    Jincheng Zhang · 2026 · Zenodo (CERN European Organization for Nuclear Research)

    Quantum decoherence, the spontaneous loss of quantum information, represents a significant challenge to the practical implementation of quantum technologies. This research explores the potential of leveraging decoherence to create secure communication channels, focusing on the deliberate induction of these events and their utilization as a means of information encoding. The core concept is to design a system where decoherence is orchestrated to create vulnerabilities that are exceptionally difficult to exploit, offering a novel approach to information security.

  21. Experimental Protocol for Testing Information Transfer via Weak Measurement and Quantum Entanglement without a Classical Communication Channel

    Oleksandr Olegovich Kurmanchuk · 2026 · Zenodo (CERN European Organization for Nuclear Research)

    This document proposes a novel experimental protocol to test whether quantum information can manifest at a receiver without any classical signal, using weak measurement, post-selection, and pre-shared quantum entanglement. After systematic computational search over 6.4 billion parameter combinations, weak measurement combined with post-selection and complete isolation from classical communication was identified as the sole surviving candidate not excluded by known physics. The accompanying Jupyter notebook contains all source code and raw computational results. A positive experimental result would constitute the first empirical challenge to the no-communication theorem; a negative result clo

  22. Faster-Than-Light Communication using Quantum Entanglement is Possible

    Florentin Smarandache · 2025 · Information Sciences with Applications

    In this little note we refute the statement that Faster-Than-Light Communication using Quantum Entanglement is Impossible, by proving that the alleged proof of the mainstream is irrelevant. Also, the Faster-Than-Light Communication does NOT mean sending information into the past. We recall the many paradoxes of the theory of relativity that make it unrealistic, while the Absolute Theory of Relativity [1] is the realistic one.
