Bringing quantum revolutions to the classroom

Bringing quantum revolutions to the classroom

Media and even politics regularly talk about quantum technologies as one of the big upcoming innovations. It is even said that we are going through a quantum revolution. But did you know that most modern technologies that we use on a daily basis already rely on...

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, quantum internet.

Anomalous decay of coherence in a dissipative many-body system

Anomalous decay of coherence in a dissipative many-body system

 Bose-Einstein condensates team of our lab study the loss of spatial coherence of bosonic atoms in an optical lattice when subjected to a controlled amount of spontaneous emission. Ytterbium atoms are promoted to an excited state by a near-resonant laser and decay...

After the proton, now the deuteron

After the proton, now the deuteron

Again, the “deuteron radius” is smaller than expected anfd in good agreement with the “proton radius” deduced from muonic hydrogen spectroscopy, thus reinforcing the “proton radius puzzle”.
