Quantum-enhanced physical-layer threat detection in metropolitan-scale fiber networks
Yung-Cheng Kao, Siddharth Pal, Alex Forencich +8
Network security is widely recognized as a key application of quantum technology. However, its large-scale deployment is hindered by the need for tight coordination between fundame…
Quantum-enhanced quickest change detection of transmission loss
Saikat Guha, Tiju Cherian John, Zihao Gong +1
Augmenting a train of bright phase-modulated laser-light pulses of a coherent communications system with infinitesimally small quantum photons per pulse -- entangled across several…
A Quantum Speedup in Localizing Transmission Loss Change in Optical Networks
Yufei Zheng, Yu-Zhen Janice Chen, Prithwish Basu +1
The ability to localize transmission loss change to a subset of links in optical networks is crucial for maintaining network reliability, performance and security. \emph{Quantum pr…
Efficient Direct-Connect Topologies for Collective Communications
Liangyu Zhao, Siddharth Pal, Tapan Chugh +5
We consider the problem of distilling efficient network topologies for collective communications. We provide an algorithmic framework for constructing direct-connect topologies opt…
