Heuristic lower bounds on real Grothendieck constants of finite and infinite order

Erika Bene, Tamás Vértesi

We propose candidate lower bounds on the real Grothendieck constants and their infinite-dimensional limit using rotationally invariant cubic kern…

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…

Bound entanglement-assisted prepare-and-measure scenarios based on four-dimensional quantum messages

István Márton, Erika Bene, Tamás Vértesi

We present a class of linear correlation witnesses that detects bound entanglement within a three-party prepare-and-measure scenario with four-dimensional quantum messages. We rela…
