Machine learning meets the CHSH scenario
Gabriel Pereira Alves, Nicolas Gigena, Jędrzej Kaniewski
In this work, we perform a comprehensive study of the machine learning (ML) methods for the purpose of characterising the quantum set of correlations. As our main focus is on asses…
Extremal points of the quantum set in the CHSH scenario: conjectured analytical solution
Antoni Mikos-Nuszkiewicz, Jędrzej Kaniewski
Quantum mechanics may revolutionise many aspects of modern information processing as it promises significant advantages in several fields such as cryptography, computing and metrol…
Biased Random Access Codes
Gabriel Pereira Alves, Nicolas Gigena, Jędrzej Kaniewski
A random access code (RAC) is a communication task in which the sender encodes a random message into a shorter one to be decoded by the receiver so that a randomly chosen character…
Quantum value for a family of -like Bell functionals
N. Gigena, J. Kaniewski
We introduce a three-parameter family of Bell functionals that extends those studied in reference [Phys. Rev. Research 2, 033420 (2020)] by including a marginal contribution. An an…
Optimality of any pair of incompatible rank-one projective measurements for some non-trivial Bell inequality
Gabriel Pereira Alves, Jędrzej Kaniewski
Bell non-locality represents one of the most striking departures of quantum mechanics from classical physics. It shows that correlations between space-like separated systems allowe…
Mutually unbiased bases and symmetric informationally complete measurements in Bell experiments
Armin Tavakoli, Máté Farkas, Denis Rosset +2
Mutually unbiased bases (MUBs) and symmetric informationally complete projectors (SICs) are crucial to many conceptual and practical aspects of quantum theory. Here, we develop the…
Self-testing quantum systems of arbitrary local dimension with minimal number of measurements
Shubhayan Sarkar, Debashis Saha, Jędrzej Kaniewski +1
Bell nonlocality as a resource for device independent certification schemes has been studied extensively in recent years. The strongest form of device independent certification is…
Robust self-testing of two-qubit states
Tim Coopmans, Jędrzej Kaniewski, Christian Schaffner
It is well-known that observing nonlocal correlations allows us to draw conclusions about the quantum systems under consideration. In some cases this yields a characterisation whic…
Self-testing mutually unbiased bases in the prepare-and-measure scenario
Máté Farkas, Jędrzej Kaniewski
Mutually unbiased bases (MUBs) constitute the canonical example of incompatible quantum measurements. One standard application of MUBs is the task known as quantum random access co…
Secure bit commitment from relativistic constraints
Jędrzej Kaniewski, Marco Tomamichel, Esther Hänggi +1
We investigate two-party cryptographic protocols that are secure under assumptions motivated by physics, namely relativistic assumptions (no-signalling) and quantum mechanics. In p…
