Asymptotic performance of port-based teleportation
Matthias Christandl, Felix Leditzky, Christian Majenz +3
Quantum teleportation is one of the fundamental building blocks of quantum Shannon theory. While ordinary teleportation is simple and efficient, port-based teleportation (PBT) enab…
A Quantum Multiparty Packing Lemma and the Relay Channel
Dawei Ding, Hrant Gharibyan, Patrick Hayden +1
Optimally encoding classical information in a quantum system is one of the oldest and most fundamental challenges of quantum information theory. Holevo's bound places a hard upper…
Matrix product states and the quantum max-flow/min-cut conjectures
Fulvio Gesmundo, J. M. Landsberg, Michael Walter
In this note we discuss the geometry of matrix product states with periodic boundary conditions and provide three infinite sequences of examples where the quantum max-flow is stric…
