Trade--off relations for operation entropy of complementary quantum channels
Jakub Czartowski, Daniel Braun, Karol Życzkowski
The entropy of a quantum operation, defined as the von Neumann entropy of the corresponding Choi-Jamiołkowski state, characterizes the coupling of the principal system with the env…

Iso-entangled mutually unbiased bases, symmetric quantum measurements and mixed-state designs
Jakub Czartowski, Dardo Goyeneche, Markus Grassl +1
Discrete structures in Hilbert space play a crucial role in finding optimal schemes for quantum measurements. We solve the problem whether a complete set of five iso-entangled mutu…
