Recent progress in cooling nanomechanical oscillators and the quest to explore their quantum regime has lead to the development of a large variety of nanomechanical structures offering excellent control- and tunability. True quantum properties of nanomechanical oscillators have however not yet been shown in experiments.
In our research we explore the preparation, verification and applications of non-classical states of mechanical motion. On the one hand these may serve as a test for the still debated validity of Quantum Mechanics for mesoscopic or even macroscopic devices. On the other hand they may have promising technological applications such as ultra-sensitive force sensing or storing and processing information.
