Information backflow may not indicate quantum memory
Michal Banacki, Marcin Marciniak, Karol Horodecki +1
We analyze recent approaches to quantum Markovianity and how they relate to the proper definition of quantum memory. We point out that the well-known criterion of information backf…
Optimal allocation of quantum resources
Roberto Salazar, Tanmoy Biswas, Jakub Czartowski +2
The optimal allocation of resources is a crucial task for their efficient use in a wide range of practical applications in science and engineering. This paper investigates the opti…
Blurred quantum Darwinism across quantum reference frames
Thao P. Le, Piotr Mironowicz, Paweł Horodecki
Quantum Darwinism describes objectivity of quantum systems via their correlations with their environment--information that hypothetical observers can recover by measuring the envir…
Five open problems in quantum information
Paweł Horodecki, Łukasz Rudnicki, Karol Życzkowski
We identify five selected open problems in the theory of quantum information, which are rather simple to formulate, were well-studied in the literature, but are technically not eas…
