The final results of the MICROSCOPE mission reach record precision

The final results of the MICROSCOPE mission reach record precision     The MICROSCOPE mission has just confirmed the principle of equivalence with a record precision of a few 10-15. It thus proves that bodies fall in vacuum with the same acceleration regardless...
SUPERFLUID HELIUM AND NEGATIVE PRESSURES

SUPERFLUID HELIUM AND NEGATIVE PRESSURES

SUPERFLUID HELIUM AND NEGATIVE PRESSURES     Low temperature liquid helium-4 is a model material for condensed matter physics for two reasons. First, atomic interactions are weak and quantum effects play an important role on the macroscopic scale. Secondly,...

Fundamental constants: the molecular hydrogen ion joins the play

Fundamental constants: the molecular hydrogen ion joins the play The HD+ molecule, composed of a proton, a deuteron and an electron, is along with its isotopes such as H2+ or D2+, the simplest molecule. As such, it is a valuable tool to test our understanding of...

Connecting the quantum internet

Connecting the quantum internet Researchers at the Kastler Brossel Laboratory in Paris have succeeded in implementing a novel “hybrid” entanglement swapping protocol, bringing within reach the connection of disparate platforms in a future, heterogeneously-structured,...
