Joint GKP Encoding for GHZ States Transmission over Bosonic Quantum MIMO Channels
Seid Koudia, Selssabil Kadid, Symeon Chatzinotas +1
We study transmission of a Greenberger-Horne-Zeilinger (GHZ) state over nonunitary quantum multiple-input multiple-output (QuMIMO) channels using finite-energy Gottesman-Kitaev-Pre…
Sentinel-Based Failover for QKD-Augmented IPsec Tunnels
Juan Carlos Hernandez-Hernandez, Francesco Vista, Haftay Gebreslasie Abreha +3
Quantum-safe IPsec through hybrid key establishment is practical, but creates a critical operational challenge: how to maintain tunnel availability when the QKD infrastructure beco…
Quantum Decision Theory for Displacement Detection with Finite-Energy GKP States
Seid Koudia, Symeon Chatzinotas
We develop a quantum-decision-theoretic framework for detecting phase-space displacements with finite-energy, -level Gottesman-Kitaev-Preskill (GKP) probes. For single-mode and…
Measurement-Based Loss Tolerance in Graph-GKP Codes through Syndrome-Resolved Pauli-Frame Decoding
Seid Koudia, Symeon Chatzinotas
Graph codes offer multiple physical representatives of logical observables, while Gottesman-Kitaev-Preskill (GKP) codes retain analog information about bosonic displacement noise.…
A Slow-Time Receiver Interface for Turbulent Free-Space Quantum Polarization Links
Heyang Peng, Seid Koudia, Symeon Chatzinotas
Atmospheric turbulence makes free-space quantum polarization links intrinsically time varying, whereas receiver-side reduced interfaces are often treated as static. This paper deve…
Quantum MIMO Channel Modeling in Turbulent Free-Space Optical Links
Heyang Peng, Seid Koudia, Semih Oktay +2
Free-space optical (FSO) links supporting spatial multiplexing provide a natural physical realization of Quantum MIMO channels. We develop a first-principles model for Quantum MIMO…
