Compact convex structure of measurements and its applications to simulability, incompatibility, and convex resource theory of continuous-outcome measurements
Yui Kuramochi
We introduce the post-processing preorder and equivalence relations for general measurements on a possibly infinite-dimensional general probabilistic theory described by an order u…

Compatibility of any pair of 2-outcome measurements characterizes the Choquet simplex
Yui Kuramochi
For a compact convex subset of a locally convex Hausdorff space, a measurement on is a finite family of positive elements in normalized to the unit constant $1_K…

Post-processing minimal joint observables
Teiko Heinosaari, Yui Kuramochi
A finite set of quantum observables (positive operator valued measures) is called compatible if these observables are marginals of a some observable, called a joint observable of t…

Entanglement-breaking channels with general outcome operator algebras
Yui Kuramochi
A unit-preserving and completely positive linear map, or a channel, between -algebras and $\mathcal{A}_{\m…
