Demultiplexing Generalized Information via Quantum Transmission Lines
Soham Sau, Anna Jenčová, 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 Jenčová
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…
Coherent configurations and Frobenius structures
Gejza Jenča, Anna Jenčová, Dominik Lachman
We prove that coherent configurations can be represented as modules over Frobenius structures in the category of real nonnegative matrices. We generalize the notion of admissible m…
--Rényi divergences in von Neumann algebras: data-processing inequality, reversibility, and monotonicity properties in
Fumio Hiai, Anna Jenčová
We study the --Rényi divergences where () for normal positive functionals on general von Neumann algebras, introduced in [S.~Kato and Y.~…
Geometric and algebraic aspects of spectrality in order unit spaces: a comparison
Anna Jenčová, Sylvia Pulmannová
Two approaches to spectral theory of order unit spaces are compared: the spectral duality of Alfsen and Shultz and the spectral compression bases due to Foulis. While the former ap…
Incompatible measurements in a class of general probabilistic theories
Anna Jenčová
We study incompatibility of measurements and its relation to steering and nonlocality in a class of finite dimensional general probabilistic theories (GPT).The basic idea is to rep…
On monoids in the category of sets and relations
Anna Jenčová, Gejza Jenča
The category is the category of sets (objects) and relations (morphisms). Equipped with the direct product of sets, is a monoidal category. Moreover,…
