Demultiplexing Generalized Information via Quantum Transmission Lines
Soham Sau, Anna JenÄová, Tamal Guha
Demultiplexers are the fundamental primitives of network architecture, enabling perfect routing of an input classical signal to a designated one, among multiple output ports. Quant…

Order structure and signalling in higher order quantum maps
Anna JenÄová
We study the signalling structure of higher order quantum maps from an order-theoretic perspective, building on the combinatorial characterization of higher order types by Bisio an…

--Rényi divergences in von Neumann algebras: data-processing inequality, reversibility, and monotonicity properties in
Fumio Hiai, Anna JenÄová
We study the --Rényi divergences where () for normal positive functionals on general von Neumann algebras, introduced in [S.~Kat…
