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…
The Multiqubit Elegant Joint Measurement
Jef Pauwels, Nicolas Gisin
The Elegant Joint Measurement (EJM) is a highly symmetric, partially entangled two-qubit measurement whose local marginals form a regular tetrahedron on the Bloch sphere and which…
Symmetric Localizable Multipartite Quantum Measurements from Pauli Orbits
Jef Pauwels, Cyril Branciard, Alejandro Pozas-Kerstjens +1
While the structure of entangled quantum states is relatively well understood, the characterization of entangled measurements, especially in multipartite and high-dimensional setti…
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 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…
