The rank of contextuality
Karol Horodecki, Jingfang Zhou, Maciej Stankiewicz +6
Quantum contextuality is one of the most recognized resources in quantum communication and computing scenarios. We provide a new quantifier of this resource, the rank of contextual…
Dephasing superchannels
Zbigniew Puchała, Kamil Korzekwa, Roberto Salazar +2
We characterise a class of environmental noises that decrease coherent properties of quantum channels by introducing and analysing the properties of dephasing superchannels. These…
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…
Limitations for private randomness repeaters
Karol Horodecki, Ryszard P. Kostecki, Roberto Salazar +1
Cryptographic protocols are often based on the two main resources: private randomness and private key. In this paper, we develop a relationship between these two resources. First,…
Universal structure of objective states in all fundamental causal theories
Carlo Maria Scandolo, Roberto Salazar, Jarosław K. Korbicz +1
A crucial question is how objective and classical behavior arises from a fundamental physical theory. Here we provide a natural definition of a decoherence process valid in all cau…
A No-go theorem for device-independent security in relativistic causal theories
Roberto Salazar, Michał Kamon, Dardo Goyeneche +4
A crucial task for secure communication networks is to determine the minimum of physical requirements to certify a cryptographic protocol. A widely accepted candidate for certifica…
