Certifying asymmetry in the configuration of three qubits
Abdelmalek Taoutioui, Gábor Drótos, Tamás Vértesi
Symmetry restrictions limit the types of tasks that can be achieved with a given set of quantum states. Therefore, any breaking of these symmetries could potentially be exploited a…

Self-testing of semisymmetric informationally complete measurements in a qubit prepare-and-measure scenario
Gábor Drótos, Károly F. Pál, Tamás Vértesi
Self-testing is a powerful method for certifying quantum systems. Initially proposed in the device-independent (DI) setting, self-testing has since been relaxed to the semi-device-…

Classical bounds on two-outcome bipartite Bell expressions and linear prepare-and-measure witnesses: Efficient computation in parallel environments such as graphics processing units
István Márton, Erika Bene, Péter Diviánszky +1
The presented program aims at speeding up the brute force computation of the so-called norm of a matrix using graphics processing units (GPUs). Alternatives for CPUs have…
