​Abstract:​Superconducting levitation is a fascinating phenomenon. Objects levitated in this way become extremely isolated from the environment, they have no internal mechanical losses, they can be manipulated by magnetic fields, and can be coupled to superconducting

quantum circuits. These advantages can be employed to generate quantum states with large, and massive objects, such as the proverbial SchrÅNodinger cat. Indeed, levitated superconductors have been proposed as a promising platform for macroscopic quantum

experiments.

Furthermore, due to their extreme isolation, a levitated superconducting microparticle is extremely sensitive to external perturbations. This means that they could be used as very precise force and acceleration sensors. 

In this presentation, we show the first steps towards realizing such experiments. I will introduce the working principle of superconducting levitation, show proof of concept of superconducting levitation on a chip, the progress so far, the challenges, and the outlook

for this experiment.
