Consistency of quantum computation and the equivalence principle
Marcin Nowakowski
The equivalence principle, being one of the building blocks of general relativity, seems to be also crucial for analysis of quantum effects in gravity. In this paper we consider th…
Bipartite quantum measurements with optimal single-sided distinguishability
Jakub Czartowski, Karol Życzkowski
We analyse orthogonal bases in a composite Hilbert space describing a bipartite quantum system and look for a basis with optimal single-sided mutual state distinguishab…
Multiport based teleportation -- transmission of a large amount of quantum information
Piotr Kopszak, Marek Mozrzymas, Michał Studziński +1
We analyse the problem of transmitting a number of unknown quantum states or one composite system in one go. We derive a lower bound on the performance of such process, measured in…
Self-testing mutually unbiased bases in higher dimensions with space-division multiplexing optical fiber technology
Máté Farkas, Nayda Guerrero, Jaime Cariñe +2
In the device-independent quantum information approach, the implementation of a given task can be self-tested solely from the recorded statistics and without detailed models for th…
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…
Upper bounds on device-independent quantum key distribution
Matthias Christandl, Roberto Ferrara, Karol Horodecki
Quantum key distribution (QKD) is a method that distributes a secret key to a sender and a receiver by the transmission of quantum particles (e.g. photons). Device-independent quan…
Single trusted qubit is necessary and sufficient for quantum realisation of extremal no-signaling correlations
Ravishankar Ramanathan, Michał Banacki, Ricard Ravell Rodríguez +1
Quantum statistics can be considered from the perspective of postquantum no-signaling theories in which either none or only a certain number of quantum systems are trusted. In thes…
Log-Convex set of Lindblad semigroups acting on -level system
Fereshte Shahbeigi, David Amaro-Alcalá, Zbigniew Puchała +1
We analyze the set of mixed unitary channels represented in the Weyl basis and accessible by a Lindblad semigroup acting on an -level quantum system. General nece…
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,…
A universal scheme for robust self-testing in the prepare-and-measure scenario
Nikolai Miklin, Michał Oszmaniec
We consider the problem of certification of arbitrary ensembles of pure states and projective measurements solely from the experimental statistics in the prepare-and-measure scenar…
Semi-Device-Independent Random Number Generation with Flexible Assumptions
Matej Pivoluska, Martin Plesch, Máté Farkas +6
Our ability to trust that a random number is truly random is essential for fields as diverse as cryptography and fundamental tests of quantum mechanics. Existing solutions both com…
Experimental characterisation of unsharp qubit observables and sequential measurement incompatibility via quantum random access codes
Hammad Anwer, Sadiq Muhammad, Walid Cherifi +3
Unsharp measurements are increasingly important for foundational insights in quantum theory and quantum information applications. Here, we report an experimental implementation of…
