This research combines mathematical criteria based on positive maps and invariants with experimentally accessible randomized measurements. The aim is to obtain rigorous guarantees that remain useful with finite data, noise, and restricted measurement access.</p>Optimality of generalized Choi maps in M3https://giovanniscala.github.io/publication/2024/optimality-generalized-choi-maps-m3/Fri, 26 Apr 2024 00:00:00 +0000https://giovanniscala.github.io/publication/2024/optimality-generalized-choi-maps-m3/Generalizing Choi map in M3 beyond circulant scenariohttps://giovanniscala.github.io/publication/2025/generalizing-choi-map-m3/Mon, 18 Mar 2024 00:00:00 +0000https://giovanniscala.github.io/publication/2025/generalizing-choi-map-m3/
