Cisco is at the forefront of developing practical quantum networks and data centers. The event brought together industry experts to discuss the latest advancements and challenges in quantum computing, networking, and security. Cisco’s strategy focuses on creating quantum data centers that utilize numerous quantum circuits, dynamic network interconnections, and various entanglement generation protocols.
The Shift from Monolithic to Distributed Quantum Computing
Reza Nejabati’s Vision for Quantum Networks
Reza Nejabati, head of quantum research at Cisco’s advanced development group Outshift, emphasized that it is not practical to scale quantum computing monolithically to millions of qubits. Current technology suggests that a more feasible approach is the creation of a network of smaller quantum computers. These interconnected processors would be housed in a data center environment, managed by Cisco to offer services to a larger user base. This shift from a monolithic model to a distributed network is integral to Cisco’s vision for practical quantum computing.
Cisco’s concept of quantum data centers could employ traditional LAN models and fiber links to connect quantum computers. Alternatively, they might use a quantum-based network that rapidly transmits qubits through quantum servers, capable of managing commercial-grade applications. This avoids the need for customers to overhaul their existing network infrastructure, as Nejabati suggests leveraging the current fiber infrastructure for quantum entanglement while layering new control and management functions on top. The combination of these elements forms a sophisticated and robust framework for distributed computing.
QFabric: The Core of Quantum Networking
Development of Quantum Entanglement Network Fabric
Central to Cisco’s networking endeavors is the development of a quantum entanglement network fabric, known as QFabric. This system is designed to be the core of a quantum switch, ensuring effective quantum entanglement between quantum computers and sensor interconnects. The switch aims to support non-blocking switching of entangled photons across any input and output ports while supporting multiple modes of entanglement. Key features include ultra-low loss and minimal time jitter during port-to-port switching, facilitating seamless connectivity within the quantum network.
QFabric is also aimed at ensuring quantum-safe networking by enabling scalable key distribution. Cisco is working on a hybrid key management system that integrates post-quantum cryptography (PQC) and quantum key distribution (QKD). Included in this system is a quantum random number generator developed internally by Cisco, essential for robust cryptographic security. PQC involves complex cryptographic algorithms that protect quantum computers from sophisticated attacks and is anticipated to be adopted by browsers, operating systems, and libraries. Enterprises are expected to integrate PQC into security protocols like SSL/TLS 1.3 to safeguard data in a post-quantum world.
Quantum Orchestra: Orchestrating Quantum Networks
Introduction to Quantum Orchestra
Additionally, Cisco is developing a software package named Quantum Orchestra, which spans entanglement processes, distribution protocols, and routing algorithms. This package will be integral to a network-aware quantum orchestrator that processes quantum jobs and network topology, considering the distribution of quantum devices. Hassan Shapourian, Technical Leader at Cisco Outshift, explained that the orchestrator will facilitate modifying quantum circuits for better distributability, determining device assignments, and managing communication within the network.
This involves scheduling switch configurations to enable end-to-end entanglement generations, resource management, and routing, ultimately aiming to minimize execution time and switching events. Most of the current work with the Quantum Orchestra has been simulated to ensure functionality in multi-tenancy and data delivery through multiple quantum paths, with findings to be published later in the year. This ongoing development underscores Cisco’s commitment to cutting-edge solutions that can meet the demands of complex quantum networks.
