Description
Levitodynamics, where a mesoscopic particle is held in vacuum, provides a promising platform to study quantum mechanics in massive resonators. Yet, most approaches rely on the use of laser light to generate the trapping potential or measure/control the resonator, leading to bulk heating and limiting the type of object that can be levitated. Our approach leverages a Paul trap and magnetomechanical coupling to a superconducting circuit, hence removing the need for a laser. I will present our progress with the trapping at cryogenic temperatures of micron-sized magnets and their coupling to superconducting circuits. By coupling to circuits, this approach opens the circuit QED toolbox for QND measurements and quantum state preparation. Leveraging this, we propose to use this platform to prepare complex quantum states in massive mechanical resonators.
