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…
Bit Threads and Holographic Monogamy
Shawn X. Cui, Patrick Hayden, Temple He +3
Bit threads provide an alternative description of holographic entanglement, replacing the Ryu-Takayanagi minimal surface with bulk curves connecting pairs of boundary points. We us…
Efficient algorithms for tensor scaling, quantum marginals and moment polytopes
Peter Bürgisser, Cole Franks, Ankit Garg +3
We present a polynomial time algorithm to approximately scale tensors of any format to arbitrary prescribed marginals (whenever possible). This unifies and generalizes a sequence o…
Horn inequalities and quivers
Velleda Baldoni, Michèle Vergne, Michael Walter
Let G be a complex reductive group acting on a finite-dimensional complex vector space H. Let B be a Borel subgroup of G and let T be the associated torus. The Mumford cone is the…
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…
