An invertible map between Bell non-local and contextuality scenarios
Victoria J Wright, Máté Farkas
We present an invertible map between correlations in any bipartite Bell scenario and behaviours in a family of contextuality scenarios. The map takes local, quantum and non-signall…
Characterizing and quantifying the incompatibility of quantum instruments
Arindam Mitra, Máté Farkas
Incompatibility of quantum devices is one of the cornerstones of quantum theory, and the incompatibility of quantum measurements and channels has been linked to quantum advantage i…
Upper bounds on key rates in device-independent quantum key distribution based on convex-combination attacks
Karol Łukanowski, Maria Balanzó-Juandó, Máté Farkas +2
The device-independent framework constitutes the most pragmatic approach to quantum protocols that does not put any trust in their implementations. It requires all claims, about e.…
Mutually Unbiased Measurements, Hadamard Matrices, and Superdense Coding
Máté Farkas, Jędrzej Kaniewski, Ashwin Nayak
Mutually unbiased bases (MUBs) are highly symmetric bases on complex Hilbert spaces, and the corresponding rank-1 projective measurements are ubiquitous in quantum information theo…
Three numerical approaches to find mutually unbiased bases using Bell inequalities
Maria Prat Colomer, Luke Mortimer, Irénée Frérot +2
Mutually unbiased bases correspond to highly useful pairs of measurements in quantum information theory. In the smallest composite dimension, six, it is known that between three an…
