Holographic quantum codes with trapped ions
Alex Steiner, Gerard Anglès Munné, Robert Freund +9
Holography is a central concept at the intersection of gravity, condensed matter theory, and quantum information, linking the interior bulk of a system to its boundary. A model rea…
Typicality of Steering for Two-qubit States
Gerard Anglès Munné, Paweł Cieśliński, Tamás Vértesi +1
Phenomena that slip beyond the grasp of our classical intuition reveal uniquely quantum effects that deepen our understanding of the physical world and enable advances in informati…
Threshold entanglement sharing: quantum states with absolutely separable marginals
Albert Rico, Jofre Abellanet-Vidal, Naga Bhavya Teja Kothakonda +2
Motivated to understand how entanglement resources can be distributed in quantum networks, we introduce threshold entanglement (TE) states. These are multipartite quantum states wh…
SDP bounds on quantum codes: rational certificates
Gerard Anglès Munné, Felix Huber
A fundamental problem in quantum coding theory is to determine the maximum size of quantum codes of given block length and distance. A recent work introduced bounds based on semide…
