Seminarium Optyczne

Inspired by methods established within the realms of quantum optics and atomic-ion quantumtechnologies, we demonstrate a quantum-non-demolition technique for the non-destructivedetection of the internal quantum state of a single trapped molecular ion. The method is based onthe state-dependent coherent excitation of the motion of the trapped molecular ion and subsequentdetection of the motional quantum state using a co-trapped atomic ion. This new approach offersnew perspectives not only for the detection, but also for the preparation and the manipulation ofmolecular quantum states on the single-particle level with a greatly improved sensitivity comparedto previously used destructive schemes. We present a characterization of our technique using thehomonuclear diatomic species N2+ as an example, show how it can be used for non-invasivespectroscopic measurements on single molecules and discuss prospective applications in the realmof precision molecular spectroscopy.
