New publication out in Scientific Reports


Our recent work, in collaboration with the QUTIS group at the University of the Basque Country, has been published in Scientific Reports. In this paper, we report the performance of a single laser-cooled calcium ion as an optical sensor of tiny electric signals. We have also measured the upper limit of the heating rate in our system with prospects for measuring electric signals induced by any neighbouring charged particle(s).
