Discrete dynamics in the set of quantum measurements
Albert Rico, Karol Życzkowski
A quantum measurement, often referred to as positive operator-valued measurement (POVM), is a set of positive operators summing to identity, $\sum_jP_j=\mathbb{1}…

Entanglement detection with trace polynomials
Albert Rico, Felix Huber
We provide a systematic method for nonlinear entanglement detection based on trace polynomial inequalities. In particular, this allows to employ multi-partite witnesses for the det…
