Device-independent tests of structures of measurement incompatibility
(American Physical Society, 2019-10-31)
In contrast with classical physics, in quantum physics some sets of measurements are incompatible in the sense that they cannot be performed simultaneously. Among other applications, incompatibility allows for contextuality ...

Microdosimetry in low energy proton beam at therapeutic-equivalent fluence rate with silicon 3D-cylindrical microdetectors
(IOP Publishing, 2021-05)
In this work we show the first microdosimetry measurements on a low energy proton beam with therapeutic-equivalent fluence rates by using the second generation of 3D-cylindrical microdetectors. The sensors belong to an ...

Quantum Clock Synchronization with a Single Qudit
(Nature Publishing Group, 2015)
Clock synchronization for nonfaulty processes in multiprocess networks is indispensable for a variety of technologies. A reliable system must be able to resynchronize the nonfaulty processes upon some components failing ...

Loophole-Free Bell Test based on local precertification of Photon’s Presence
(American Physical Society, 2012)
A loophole-free violation of Bell inequalities is of fundamental importance for demonstrating quantumnonlocality and long-distance device-independent secure communication. However, transmission lossesrepresent a fundamental ...

Experimental demonstration of the connection between quantum contextuality and graph theory
(American Physical Society, 2016-07-20)
We report a method that exploits a connection between quantum contextuality and graph theory to reveal any form of quantum contextuality in high-precision experiments. We use this technique to identify a graph which ...

Magnetic switching of spin-scattering centers in Dresselhaus [110] circuits
(American Physical Society, 2024-01-24)
Spin carriers subject to Dresselhaus [110] (D110) spin-orbit coupling (SOC) gather null spin phases in closed circuits, contrary to usual Rashba and Dresselhaus [001] SOC. We show that D110 spin phases can be activated in ...

Irreducible magic sets for n-Qubit systems
(Physical Review Letters, 2022-11-07)
Magic sets of observables are minimal structures that capture quantum state-independent advantage for systems of n ≥ 2 qubits and are, therefore, fundamental tools for investigating the interface between classical and ...

Noncontextual wirings
(American Physical Society, 2018-03-29)
Contextuality is a fundamental feature of quantum theory necessary for certain models of quantum computation and communication. Serious steps have therefore been taken towards a formal framework for contextuality as an ...

Multidimensional entanglement generation with multicore optical fibers
(American Physical Society, 2021-03-09)
Trends in photonic quantum information follow closely the technical progress in classical optics and telecommunications. In this regard, advances in multiplexing optical communications channels have also been pursued for ...
