Multiaccess quantum communication and product higher rank numerical range
Maciej Demianowicz, Paweł Horodecki, Karol Życzkowski
In the present paper we initiate the study of the product higher rank numerical range. The latter, being a variant of the higher rank numerical range [M.--D. Choi {\it et al.}, Rep…
