Efficient entanglement distillation without quantum memory
Daniela Abdelkhalek, Mareike Syllwasschy, Nicolas J. Cerf +2
Entanglement distribution between distant parties is an essential component to most quantum communication protocols. Unfortunately, decoherence effects such as phase noise in optic…
A targeted search for point sources of EeV photons with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +397
Simultaneous measurements of air showers with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for EeV photon point sources. Several…
Measurements of top-quark pair to -boson cross-section ratios at TeV with the ATLAS detector
ATLAS Collaboration
Ratios of top-quark pair to -boson cross sections measured from proton--proton collisions at the LHC centre-of-mass energies of TeV, 8TeV, and 7TeV are presented by…
Measurement of the prompt pair production cross-section in collisions at TeV with the ATLAS detector
ATLAS Collaboration
The production of two prompt mesons, each with transverse momenta GeV and rapidity , is studied using a sample of proton-proton collisions at…
Direct method for measuring and witnessing quantum entanglement of arbitrary two-qubit states through Hong-Ou-Mandel interference
Karol Bartkiewicz, Grzegorz Chimczak, Karel Lemr
We describe a direct method for experimental determination of the negativity of an arbitrary two-qubit state with 11 measurements performed on multiple copies of the two-qubit syst…
Quantum non-Gaussianity from a large ensemble of single photon emitters
Lukáš Lachman, Radim Filip
Quantum attributes of light have been related to non-classicality so far, i. e. to incompatibility with mixtures of coherent states. The progress in quantum optics indicates that t…
