Quantum inputs in the prepare-and-measure scenario and stochastic teleportation
Elna Svegborn, Jef Pauwels, Armin Tavakoli
We investigate prepare-and-measure scenarios in which a sender and a receiver use entanglement to send quantum information over a channel with limited capacity. We formalise this f…
Quantum correlations in prepare-and-measure scenarios and their semi-device-independent applications
Jonatan Bohr Brask, Nicolas Brunner, Jef Pauwels +2
A key aspect in quantum information is to understand the advantage offered by quantum systems over classical ones in communication tasks. In recent years, a fundamental approach to…
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…
Binarisation of multi-outcome measurements in high-dimensional quantum correlation experiments
Armin Tavakoli, Roope Uola, Jef Pauwels
High-dimensional systems are an important frontier for photonic quantum correlation experiments. These correlation tests commonly prescribe measurements with many possible outcomes…
Information capacity of quantum communication under natural physical assumptions
Jef Pauwels, Stefano Pironio, Armin Tavakoli
The quantum prepare-and-measure scenario has been studied under various physical assumptions on the emitted states. Here, we first discuss how different assumptions are conceptuall…
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…
