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…
All Entangled States are Nonlocal and Self-Testable in the Broadcast Scenario
Pavel Sekatski, Jef Pauwels
Entanglement and Bell nonlocality are known to be inequivalent: there exist entangled states that admit a local hidden-variable model for all local measurements. Here we show that…
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…
Certification of quantum correlations and DIQKD at arbitrary distances through routed Bell tests
Pavel Sekatski, Jef Pauwels, Edwin Peter Lobo +2
Transmission loss represents a major obstacle to the device-independent certification of quantum correlations over long distances, limiting applications such as device-independent…
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…
Holographic (Eternal) Inflation
Thomas Hertog, Jef Pauwels, Victoria Venken
We identify a minisuperspace of complex deformations of ABJM theory for which the partition function specifies the amplitude of an eternally inflating universe. The boundary theory…
