Quantum-Classical Coexistence Network Tomography
Xuchuang Wang, Joseph C. Chapman, Aneesh Ramaswamy +5
Quantum-classical coexistence networks (QCNs) share optical fiber between quantum and classical signals via wavelength-division multiplexing, offering a practical path to quantum c…
Efficient routing and spectrum allocation in arbitrary flex-grid entanglement networks
Zachary Goisman, Matthew L. Stevens, Maxwell Goisman +7
As practical quantum networks approach large-scale deployment, the need for efficient user-to-user frequency allocation is increasing, yet current approaches only provide partial s…
Designing a Satellite Serviced Quantum Network Backbone for Concurrent Global Connectivity
Prateek Mantri, Stav Haldar, Albert Williams +1
Satellite-serviced quantum networks pose an architectural problem distinct from classical satellite networking: because entanglement cannot be copied, and long-lived buffering is t…
Quantum-enhanced Network Tomography
Yufei Zheng, Zihao Gong, Saikat Guha +1
Network tomography refers to the use of inference techniques for inferring internal network states from end-to-end probes. Quantum probes, implemented by sending blocks of cohe…
Rethinking Quantum Networking with Advances in Fiber Technology
Prateek Mantri, Michael S. Bullock, Aditya Tripathi +3
Recent comparisons of quantum repeater protocols have highlighted the strong near-term potential of multiplexed two-way architectures for long-distance quantum communication. At th…
Learnability, Identifiability, and Monitor Placement in Quantum Network Tomography
Athira Kalavampara Raghunadhan, Matheus Guedes De Andrade, Don Towsley +3
Reliable quantum communication requires accurate characterization of the quantum links. This paper studies Quantum Network Tomography (QNT) under limited monitoring resources, wher…
