NPA Seminar: Gerard Higgins, Institute for Quantum Optics and Quantum Information (IQOQI), Vienna, "Towards Quantum Tests and Dark Matter Searches with Magnetically-Levitated Superconductors"
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.
