Convex set of quantum states with positive partial transpose analysed by hit and run algorithm
Konrad Szymański, Benoît Collins, Tomasz Szarek +1
The convex set of quantum states of a composite system with positive partial transpose is analysed. A version of the hit and run algorithm is used to generate a sequen…
Bound on Bell Inequalities by Fraction of Determinism and Reverse Triangle Inequality
P. Joshi, K. Horodecki, M. Horodecki +5
It is an established fact that entanglement is a resource. Sharing an entangled state leads to non-local correlations and to violations of Bell inequalities. Such non-local correla…
Robust Device-Independent Randomness Amplification with Few Devices
Fernando G. S. L. Brandao, Ravishankar Ramanathan, Andrzej Grudka +5
Randomness amplification is the task of transforming a source of somewhat random bits into a source of fully random bits. Although it is impossible to amplify randomness from a sin…
Robust Device Independent Randomness Amplification
Ravishankar Ramanathan, Fernando G. S. L. Brandao, Andrzej Grudka +3
In randomness amplification a slightly random source is used to produce an improved random source. Perhaps surprisingly, a single source of randomness cannot be amplified at all cl…
