We generalize the notion of joint measurability to continuous variable systems by extending a recently introduced compression algorithm of quantum measurements to this realm. The e…

Barycentric decomposition for quantum instruments
Juha-Pekka Pellonpää, Erkka Haapasalo, Roope Uola
We present a barycentric decomposition for quantum instruments whose output space is finite-dimensional and input space is separable. As a special case, we obtain a barycentric dec…
