Lower bounds on bipartite entanglement in noisy graph states
Aqil Sajjad, Eneet Kaur, Kenneth Goodenough +2
Graph states are a key resource for a number of applications in quantum information theory. Due to the inherent noise in noisy intermediate-scale quantum (NISQ) era devices, it is…
Rate-Fidelity Tradeoffs in All-Photonic and Memory-Equipped Quantum Switches
Panagiotis Promponas, Leonardo Bacciottini, Paul Polakos +3
Quantum entanglement switches are a key building block for early quantum networks, and a central design question is whether near-term devices should use only flying photons or also…
Multipartite Entanglement Distribution in Quantum Networks using Subgraph Complementations
Aniruddha Sen, Kenneth Goodenough, Don Towsley
Quantum networks are important for quantum communication, enabling tasks such as quantum teleportation, quantum key distribution, quantum sensing, and quantum error correction, oft…
Measurement Strategies and Estimation Precision in Quantum Network Tomography
Athira Kalavampara Raghunadhan, Matheus Guedes De Andrade, Don Towsley +3
This work investigates measurement strategies for link parameter estimation in Quantum Network Tomography (QNT), where network links are modeled as depolarizing quantum channels di…
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…
On noise in swap ASAP repeater chains: exact analytics, distributions and tight approximations
Kenneth Goodenough, Tim Coopmans, Don Towsley
Losses are one of the main bottlenecks for the distribution of entanglement in quantum networks, which can be overcome by the implementation of quantum repeaters. The most basic fo…
