HI-QDC: An Isometric Modular Scalable Architecture for Quantum Data Centers
Mohadeseh Azari, Anoosha Fayyaz, Amy Babay +3
Server-centric quantum data-center architectures offer scalability by distributing communication tasks across QPUs rather than concentrating complexity in a centralized switching c…
Sequential vs. Synchronized Entanglement Swapping: QKD Secret-Key Rate under Optimized Link-Layer Control
Priyam Srivastava, Akshat R. Sabavat, Siddharth Jain +6
Quantum repeater chains build long-distance entanglement for quantum key distribution (QKD) by creating pairs on short links and joining them through entanglement swapping. Because…
To Purify or Not to Purify: Entanglement Purification under Input Fidelity Asymmetry in Quantum Networks
Anoosha Fayyaz, Prashant Krishnamurthy, Kaushik Seshadreesan +2
Entanglement purification with two entangled resource pairs is widely employed in the literature on quantum repeater networks to counteract fidelity degradation introduced by noisy…
Toward Hop-Independent Fidelity in Quantum Data Centers: Resource Requirements for Entanglement Purification
Mohadeseh Azari, Anoosha Fayyaz, Amy Babay +3
Quantum data-center networks must distribute entanglement between QPUs over paths whose length grows with system scale, but each entanglement-swapping step reduces the quality of t…
Fidelity-Guaranteed Entanglement Routing with Distributed Purification Planning
Anthony Gatti, Anoosha Fayyaz, Prashant Krishnamurthy +2
Many quantum-network applications require end-to-end Bell pairs whose fidelity exceeds a request-specific threshold, but existing entanglement routing algorithms either optimize on…
Comparing GHZ-Based Strategies for Multipartite Entanglement Distribution in 2D Repeater Networks
Mohadeseh Azari, Amy Babay, Prashant Krishnamurthy +1
We conduct a comparative study to determine the initial quality necessary to extend the distance range of an -qubit GHZ state (the parent state) using two-dimensional repeaters.…
On Selecting Paths for End-to-End Entanglement Creation in Quantum Networks
Anoosha Fayyaz, Prashant Krishnamurthy, Kaushik P. Seshadreesan +2
Optimal routing is a fundamental challenge in quantum networking, with several approaches proposed to identify the most efficient path for end-to-end (e2e) entanglement generation…
