Where to Decide: Control-Plane Geometry in Coherence-Limited Quantum Networks
I. Dey, N. Marchetti
Quantum networks are usually framed by two hardware limits: how fast entanglement can be heralded, and how long a memory can hold it. We establish a third, geometric limit: entangl…
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…
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…
QMA Complete Quantum-Enhanced Kyber: Provable Security Through CHSH Nonlocality
Ilias Cherkaoui, Indrakshi Dey
Post-quantum cryptography (PQC) must secure large-scale communication systems against quantum adversaries where classical hardness alone is insufficient and purely quantum schemes…
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…
Classical Capacity of Arbitrarily Distributed Noisy Quantum Channels
Indrakshi Dey, Harun Siljak, Nicola Marchetti
With the rapid deployment of quantum computers and quantum satellites, there is a pressing need to design and deploy quantum and hybrid classical-quantum networks capable of exchan…
Entanglement Distribution and Quantum Teleportation in Higher Dimension over the Superposition of Causal Orders of Quantum Channels
Indrakshi Dey, Nicola Marchetti
Multiple photonic degrees of freedom can be explored to generate high-dimensional quantum states; commonly referred to as `qudits'. Qudits offer several advantages for quantum comm…
Quantum Channel Modelling by Statistical Quantum Signal Processing
Mouli Chakraborty, Harun Siljak, Indrakshi Dey +1
In this paper we are interested to model quantum signal by statistical signal processing methods. The Gaussian distribution has been considered for the input quantum signal as Gaus…
