Magnetically-levitated superconductors make an excellent platform for tests of quantum physics with large particles and for quantum sensing. The superconducting particles are highly-isolated from their surroundings, in ultrahigh vacuum, at cryogenic temperatures, within dissipationless traps. The particle motion can be coupled to superconducting quantum circuits, offering the potential for sensing the motion below the standard quantum limit, and for preparing quantum states of motion.
I will describe our progress in developing this platform, and its prospects for probing gravitational effects in quantum systems and for searching for well-motivated dark matter candidates.
