Abstract: Multipartite entanglement -- namely, entanglement shared between more than two parties -- represents a powerful resource for quantum networks. Indeed, multipartite entanglement enables a new form of connectivity, referred to as entanglement-enabled connectivity, which augments the connectivity enabled by the physical topology with artificial links between pairs of remote nodes -- i.e., nodes that are not neighbor in the physical topology -- without any additional physical link deployment. Thus, multipartite entanglement enables a richer, dynamic overlay topology, referred to as "artificial topology", upon the physical one.

Abstract: The presentation focuses on EuroQCI network deployments and challenges with the installation and integration of QKD devices in operational network environment. Based on PIONIER-Q, Polish QCI network, experience with single photon devices is presented and discussed. Challenges with Key Management Network design, deployment, implementation and integration will be discussed. EuroQCI national QCI networks are first step to larger scale adoption of single photon devices and evolution toward general quantum communication schemes and systems based on entanglement based devices. Number of existing QKD use cases and application can be scaled and adopted for future general quantum communication systems.

Abstract: Quantum networks are envisioned to achieve novel capabilities that are provably impossible using classical networks and could be transformative to science, economy, and national security. These novel capabilities range from cryptography, sensing and metrology, distributed systems, to secure quantum cloud computing. Today, quantum networks are in their infancy. Like the Internet, quantum networks are expected to undergo different stages of research and development until they reach a level of practical functionality.
The U.S. Department of Energy (DOE) is funding a collaborative effort involving Berkeley Lab (LBNL), UC Berkeley (UCB), Caltech, and the University of Innsbruck to develop a quantum networking testbed known as QUANT-NET. This initiative aims to establish a testbed network between LBNL and UCB, utilizing an entanglement swapping substrate over approximately 5 km of optical fiber, managed by a quantum network protocol stack. The project will implement foundational elements of distributed quantum computing and quantum repeaters, including the teleportation of a controlled-NOT gate between two distant trapped-ion quantum computation nodes.
In this presentation, I will first outline the vision and current status of the QUANT-NET project. Subsequently, I will explore the opportunities for standardizing quantum network protocols, which are crucial for the future interoperability and scalability of quantum networks.

Abstract: The U.S. Department of Energy (DOE) currently supports Berkeley Lab (LBNL), UC Berkeley (UCB), Caltech, and the University of Innsbruck in constructing a testbed for quantum networking technologies (QUANT-NET). The goal is to establish a testbed network between LBNL and UCB, where both sites are connected with an entanglement swapping substrate over ∼5 km optical fiber and managed by a quantum network protocol stack. On top of this entanglement swapping substrate the research team will implement the most basic building blocks of distributed quantum computing and quantum repeaters by teleporting a controlled-NOT gate between two far trapped-ion quantum computation nodes. Quantum network control is a major research area of the QUANT-NET project. We strive to: (i) build a quantum network control plane to orchestrate and manage all the physical layer technologies, and (ii) explore what a quantum network control plane should look like in the future, so as to automate high-rate and high-fidelity entanglement generation, distribution, and storage in an efficient, reliable, and cost-effective way. To these ends, we have designed a two-level control framework for quantum networks. Within such a framework, a two-level scheduler has been implemented to support TDMA-like (Time Division Multiple Access) scheduling, network-wide non-real-time control, and node-wide real-time control. This two-level control framework and the scheduler have been designed to address the basic needs for quantum network control. In addition, the implementation of the control plane adopts a modular and extensible framework that allows user-defined plugins. The control framework and the scheduler are not only designed specifically for the QUANT-NET testbed, but can also be extended to support other types of quantum networks. In this talk, I will present the two-level control framework and the scheduler. I will first discuss the basic needs of a quantum network control plane. Next, I will present the design and implementation of the two-level control framework and the scheduler.
