Bell and EPR experiments with signalling data
Lucas Maquedano, Sophie Egelhaaf, Amro Abou-Hachem +4
The no-signalling principle is a fundamental assumption in Bell-inequality and quantum-steering experiments. Nonetheless, experimental imperfections can lead to apparent violations…

Quantum stochastic communication via high-dimensional entanglement
Chao Zhang, Jia-Le Miao, Xiao-Min Hu +6
Entanglement has the ability to enhance the transmission of classical information over a quantum channel. However, fully harvesting this advantage typically requires complex entang…

Prepare-and-measure scenarios with photon-number constraints
Carles Roch i Carceller, Jef Pauwels, Stefano Pironio +1
We study correlations in the prepare-and-measure scenario when quantum communication is constrained by photon-number statistics. Such constraints are natural and practical control…
