Our immediate goal is to cool a magnetically-levitated particle to the ground state, and from there to study quantum states of motion. To this end, we also aim to couple the particle's motion to a flux-tunable superconducting microwave resonator - which offers a higher read-out sensitivity – and facilitates access to the rich toolbox of optomechanical control protocols.
*This work was supported in part by the EU Horizon Europe project SuperMeQ (no.~101080143), the QuantERA project C'MON-QSENS!, the Knut and Alice Wallenberg Foundation through a Wallenberg Academy Fellowship (W.W.), by the Wallenberg Center for Quantum Technology (WACQT, A.P.), by Chalmers Excellence Initiative Nano, and by the Swedish Research Council (Grant 2020-00381, G.H.). Sample fabrication was performed in the Myfab Nanofabrication Laboratory at Chalmers. Simulations were performed on resources provided by the Swedish National Infrastructure for Computing (SNIC) at Tetralith, Linköping University, partially funded by the Swedish Research Council (Grant 2018-05973).
