Quantum clock synchronization with a single qudit
(Nature Research, 2015-01-23)
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 ...

Two fundamental experimental tests of nonclassicality with qutrits
(Nature Research, 2013-07-10)
We report two fundamental experiments on three-level quantum systems (qutrits). The first one tests the simplest task for which quantum mechanics provides an advantage with respect to classical physics. The quantum advantage ...

Experimental certification of sustained entanglement and nonlocality after sequential measurements
(American Physical Society, 2020-04)
Entanglement is a fundamental resource for quantum information science. However, bipartite entanglement is destroyed when one particle is observed via projective (sharp) measurements, as is typically the case in most ...

Experimental implementation of a Kochen-Specker Set of Quantum Tests
(American Physical Society, 2013)
The conflict between classical and quantum physics can be identified through a series of yes-no tests onquantum systems, without it being necessary that these systems be in special quantum states. Kochen-Specker (KS) sets ...

All-versus-nothing proof of Einstein-Podolsky-Rosen steering
(Nature Research, 2013-07-05)
Einstein-Podolsky-Rosen steering is a form of quantum nonlocality intermediate between entanglement and Bell nonlocality. Although Schro¨dinger already mooted the idea in 1935, steering still defies a complete understanding. ...

Weak measurements for reutilizing entanglement
(2020)
Weak measurements are a relevant tool for quantum information because they allow tuning the disturbance on the observed state and the amount of information extracted from it. They can be used to harness repeatedly a quantum ...
