Abstract:
Are the laws of quantum physics applicable to macroscopic objects of any size? This overarching question lies at the heart of current research, which aims to provide deep insights into the nature of quantum mechanics, enable the creation of delocalized superposition states of massive objects, and develop techniques to push the boundary between the quantum and classical realms.
At the University of Innsbruck, we are addressing this question by employing levitated particles in well-isolated environments. We levitate nanoparticles in Paul traps and control their external motion using feedback cooling techniques. In this seminar, I will focus on our recent efforts with levitated diamond particles that host Nitrogen-Vacancy (NV) center spin states. Diamond levitation can allow for coherent coupling between the particle’s external motion and the spin state of a single NV center embedded in the diamond — a promising approach in the quest to prepare macroscopic quantum states of motion.
