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…
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.…
Quantum Reservoir Computing: Recent Advances and Future Directions
Shehbaz Tariq, Muhammad Talha, Arshid Ali +2
Quantum reservoir computing (QRC) uses the dynamics of a fixed or weakly tuned quantum system to transform temporal and sequential inputs into measured features, while training is…
Quantum Key Distribution Without Shared Reference Frame Under Unital Noise
Junaid ur Rehman, Shehbaz Tariq, Symeon Chatzinotas
We consider a general and practical scenario of quantum key distribution (QKD) over an unknown, stationary, unital qubit channel. Furthermore, due to practical limitations, e.g., r…
Optimal GHZ-State Distribution in LOSR Quantum Networks via Local Decoding from Information Sets
Leonardo Oleynik, Shehbaz Tariq, Symeon Chatzinotas
Distributing multipartite entanglement is a prerequisite for scalable quantum networks. Networks restricted to local operations and shared randomness (LOSR) avoid the quantum-memor…
