“…Quantum communication and quantum networks are topics of utmost importance for the future of the Internet and classical communication. Several papers [3], [4] show how a Quantum Internet will work alongside the classical one over the foreseeable future. The main idea is to leverage quantum phenomena such as entanglement to design and implement algorithms and protocols that do not have classical equivalents.…”

“…The first relies on new classical algorithms that shall be designed to be quantum-resistant and replace the current public-key ones. Some examples are SPHINCS +2 and Dilithium 3 for digital signatures, and NTRU 4 for key exchange. These algorithms have been submitted to the National Institute of Standards and Technology (NIST) PQC challenge 5 for replacing and standardising the new quantum-resistant public-key cryptographic algorithms.…”

Toward a Complete Software Stack to Integrate Quantum Key Distribution in a Cloud Environment

The coming advent of Quantum Computing promises to jeopardize current communications security, undermining the effectiveness of traditional public-key based cryptography. Different strategies (Post-Quantum or Quantum Cryptography) have been proposed to address this problem. Many techniques and algorithms based on quantum phenomena have been presented in recent years; the most relevant example is the introduction of Quantum Key Distribution (QKD). This approach allows to exchange cryptographic keys among parties and does not suffer from the development of quantum computation. Problems arise when this technique has to be deployed and combined with modern distributed infrastructures that heavily depend on cloud and virtualisation paradigms. This paper addresses this issue by presenting a new software stack that effortlessly introduces QKD in such environments and involves a simulation tool for Quantum Key Distribution. This software stack allows for agnostic integration, monitoring, and management of QKD, independent from a specific vendor or technology. Furthermore, a QKD simulator is presented, designed, and tested. This latter contribution is suitable as a low-level testing device, as an independent software module to check QKD protocols, and as a testbed to identify future practical enhancements.

“…In contrast, the importance of modelling quantum teleportation as a communications system has only recently been highlighted. This kind of models enable a deeper understanding of this technology from the communications standpoint, which facilitates and provides guidelines for protocols and system design [6,12]. Models for quantum teleportation have been mostly developed for the QI scenario [3].…”

Multi-core quantum computing has been identified as a solution to the scalability problem of quantum computing. However, interconnecting quantum chips is not trivial, as quantum communications have their share of quantum weirdness: quantum decoherence and the no-cloning theorem makes transferring qubits a harsh challenge, where every extra nanosecond counts and retransmission is simply impossible. In this paper, we present our first steps towards thorough modeling of quantum communications for multicore quantum computers, which may be considered as a middle point between the well-known paradigms of Quantum Internet and Network-on-Chip. In particular, we stress the deep entanglement that exists between latency and error rates in quantum computing, and how this affects the quantum network design for this scenario. Moreover, we show the concomitant trade-off between computation and communication resources for a set of parameters out of state-of-the-art experimental research. The observed behavior lets us foresee the potential of multi-core quantum architectures.

“…Taking the development of the classical internet for reference, the next step toward a future quantum internet is to establish reliable qubit transmission between quantum nodes. As quantum decoherence is inevitable in a quantum network [25], [26], this motivates us to study the quantum version of reliable transmission control protocol.…”

A quantum network, which involves multiple parties pinging each other with quantum messages, could revolutionize communication, computing and basic sciences. The future internet will be a global system of various packet switching quantum and classical networks and we call it quantum internet. To build a quantum internet, unified protocols that support the distribution of quantum messages within it are necessary. Intuitively one would extend classical internet protocols to handle quantum messages. However, classical network mechanisms, especially those related to error control and reliable connection, implicitly assume that information can be duplicated, which is not true in the quantum world due to the no-cloning theorem and monogamy of entanglement. In this paper, we investigate and propose protocols for packet quantum network intercommunication. To handle the packet loss problem in transport, we propose a quantum retransmission protocol based on the recursive use of a quantum secret sharing scheme. Other internet protocols are also discussed. In particular, the creation of logical process-to-process connections is accomplished by a quantum version of the three-way handshake protocol.
