Identifiability and Estimation Precision in Quantum Network Tomography with Imperfect Bell-State Measurements

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 measurement parameters makes identifiability non-trivial. For an n-node star network, we design probes that ensure unique identifiability an...

Quantum-Classical Coexistence Network Tomography

A tomography framework that infers per-link channel parameters of a QCN from end-to-end measurements alone and extends the approach to star-topology networks through a system of multiplicative equations across end-node pairs, together with a simple classical-signal-direction-switching protocol that resolves the remaini...
