Positive maps from the walled Brauer algebra
Maria Balanzó-Juandó, Michał Studziński, Felix Huber
We present positive maps and matrix inequalities for variables from the positive cone. These inequalities contain partial transpose and reshuffling operations, and can be understoo…
Minimal Port-based Teleportation
Sergii Strelchuk, Michał Studziński
There are two types of port-based teleportation (PBT) protocols: deterministic -- when the state always arrives to the receiver but is imperfectly transmitted and probabilistic --…
Upper bounds on the leakage of private data and operational approach to markovianity
Karol Horodecki, Michał Studziński, Ryszard P. Kostecki +2
We quantify the consequences of a private key leakage and private randomness generated during quantum key distribution. We provide simple lower bounds on the one-way distillable ke…
Square-root measurements and degradation of the resource state in port-based teleportation scheme
Michał Studziński, Marek Mozrzymas, Piotr Kopszak
Port-based teleportation (PBT) is a protocol of quantum teleportation in which a receiver does not have to apply correction to the transmitted state. In this protocol two spatially…
