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…
