Large violation of Bell inequalities using both particle and wave measurements
Daniel Cavalcanti, Nicolas Brunner, Paul Skrzypczyk +2
When separated measurements on entangled quantum systems are performed, the theory predicts correlations that cannot be explained by any classical mechanism: communication is exclu…
Semi-device-independent bounds on entanglement
Yeong-Cherng Liang, Tamas Vertesi, Nicolas Brunner
Detection and quantification of entanglement in quantum resources are two key steps in the implementation of various quantum-information processing tasks. Here, we show that Bell-t…
Nano-fabricated solid immersion lenses registered to single emitters in diamond
L. Marseglia, J. P. Hadden, A. C. Stanley-Clarke +10
We describe a technique for fabricating micro- and nano-structures incorporating fluorescent defects in diamond with a positional accuracy in the hundreds of nanometers. Using conf…
Device-independent tests of classical and quantum dimensions
Rodrigo Gallego, Nicolas Brunner, Christopher Hadley +1
We address the problem of testing the dimensionality of classical and quantum systems in a `black-box' scenario. We develop a general formalism for tackling this problem. This allo…
Wave packet evolution in non-Hermitian quantum systems
Eva-Maria Graefe, Roman Schubert
The quantum evolution of the Wigner function for Gaussian wave packets generated by a non-Hermitian Hamiltonian is investigated. In the semiclassical limit this yields…
Bound non-locality and activation
Nicolas Brunner, Daniel Cavalcanti, Alejo Salles +1
We investigate non-locality distillation using measures of non-locality based on the Elitzur-Popescu-Rohrlich decomposition. For a certain number of copies of a given non-local cor…
