Multi-partite entanglement
Michael Walter, David Gross, Jens Eisert
We give an introduction to the theory of multi-partite entanglement. We begin by describing the "coordinate system" of the field: Are we dealing with pure or mixed states, with sin…
Entanglement from Topology in Chern-Simons Theory
Grant Salton, Brian Swingle, Michael Walter
The way in which geometry encodes entanglement is a topic of much recent interest in quantum many-body physics and the AdS/CFT duality. This relation is particularly pronounced in…
Conditional Mutual Information of Bipartite Unitaries and Scrambling
Dawei Ding, Patrick Hayden, Michael Walter
One way to diagnose chaos in bipartite unitary channels is via the tripartite information of the corresponding Choi state, which for certain choices of the subsystems reduces to th…
Multipartite Entanglement in Stabilizer Tensor Networks
Sepehr Nezami, Michael Walter
Despite the fundamental importance of quantum entanglement in many-body systems, our understanding is mostly limited to bipartite situations. Indeed, even defining appropriate noti…
The Mathematics of Entanglement
Fernando G. S. L. Brandao, Matthias Christandl, Aram W. Harrow +1
These notes are from a series of lectures given at the Universidad de Los Andes in Bogotá, Colombia on some topics of current interest in quantum information. While they aim to be…
Entanglement-assisted capacities of compound quantum channels
Mario Berta, Hrant Gharibyan, Michael Walter
We study universal quantum codes for entanglement-assisted quantum communication over compound quantum channels. In this setting, sender and receiver do not know the specific chann…
