Identifiability in Quantum State, Process, and Network Tomography
Athira Kalavampara Raghunadhan, Matheus Guedes De Andrade, Don Towsley +3
Quantum State Tomography (QST), Quantum Process Tomography (QPT), and Quantum Network Tomography (QNT) are related parameter-estimation problems that aim to reconstruct different p…
Identifiability and Estimation Precision in Quantum Network Tomography with Imperfect Bell-State Measurements
Athira Kalavampara Raghunadhan, Matheus Guedes De Andrade, Don Towsley +3
We study Quantum Network Tomography (QNT) for end-to-end link-error characterization under imperfect Bell-state measurements (BSMs), where multiplicative coupling between link and…
Emulation of Entanglement Distribution Networks on a Quantum Computer
Ashley N. Tittelbaugh, Jerry Horgan, Rohan Bali +4
We investigate how quantum computers can be used to emulate quantum networks and study their performance under practical impairments. In particular, we evaluate how degraded entang…
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…
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…
Strategies for entanglement distribution in optical fiber networks
Hannah McAleese, Anuj Agrawal, Vivek Vasan +5
Distributing entanglement over long distances remains a challenge due to its fragility when exposed to environmental effects. In this work, we compare various entanglement distribu…
