Dimension witnesses and quantum state discrimination
Nicolas Brunner, Miguel Navascués, Tamás Vértesi
Dimension witnesses allow one to test the dimension of an unknown physical system in a device-independent manner, that is, without placing assumptions about the functioning of the…
Closing the detection loophole in multipartite Bell tests using GHZ states
Karoly F. Pal, Tamas Vertesi, Nicolas Brunner
We investigate the problem of closing the detection loophole in multipartite Bell tests, and show that the required detection efficiencies can be significantly lowered compared to…
All quantum states useful for teleportation are nonlocal resources
Daniel Cavalcanti, Antonio Acin, Nicolas Brunner +1
Understanding the relation between the different forms of inseparability in quantum mechanics is a longstanding problem in the foundations of quantum theory and has implications fo…
Persistency of entanglement and nonlocality in multipartite quantum systems
Nicolas Brunner, Tamas Vertesi
The behaviour under particle loss of entanglement and nonlocality is investigated in multipartite quantum systems. In particular, we define a notion of persistency of nonlocality,…
