A team of researchers at the Centre de nanosciences et de nanotechnologies - C2N (CNRS/Université Paris-Saclay) have observed for the first time the transmission of the quantum state of electrons across a micron-scale metallic island, thanks to a mechanism which freezes the overall charge of the small island. Their work is published on December 6th, 2019 in Science magazine.
