Speaker: Prof. Aruna Balasubramanian, Stony Brook University
Host: Prof. Kate Ching-Ju Lin
Abstract:
In this talk, I will first give a brief background on quantum computing and the need for quantum networks. The problem is that today’s quantum network protocols face fundamental limitations: most rely on establishing end-to-end entanglement before teleportation, which is costly to establish and is extremely short-lived. While hop-by-hop teleportation provides more flexibility, existing designs assume ideal, noise-free conditions. In effect, noise emerges as the fundamental bottleneck that affects the scalability and reliability of multi-hop quantum transmission. In this work, I show how we can use verification as a building block for multi-hop quantum communication that works well even under noise. Our verification algorithm provably detects and filters low-quality pair-wise entanglements, ensuring that only high-fidelity pairs are used for communication. I will then show how we can build on this verification to design a new quantum network stack.
Bio:
Aruna Balasubramanian is an Associate Professor at Stony Brook University (and was a visiting faculty at SUNY Korea in 2023-2024). She received her Ph.D from the University of Massachusetts Amherst, where her dissertation won the UMass outstanding dissertation award and was the SIGCOMM dissertation award runner up. She works in the area of networked systems. Her current work consists of two threads: (1) efficient and sustainable LLMs, (2) improving the accessibility of smartphones for individuals with disability, and (3) quantum networks. She is the recipient of an IMC test-of-time award, a SIGMOBILE Rockstar award, a Ubicomp best paper award, a VMWare Early Career award, and several Google research awards. She is passionate about improving the diversity in Computer Science and broadening participation. She leads the diversity committee at Stony Brook and is an active member of the N2Women group.
