Magnetically levitated particles promise to reach ultra-low mechanical dissipation [1] because of the absence of clamping and internal material losses, which are otherwise limiting factors in clamped nanomechanical resonators, and the absence of photon recoil heating, a limiting factor in optical levitation experiments. The magnetically levitated particle can be coupled via flux to superconducting circuits, which allows for quantum manipulation of its centre-of-mass (COM) motion. Thus, magnetically levitated particles are a promising novel platform for developing ultra-sensitive force and acceleration sensors, both in the classical [2] and in the quantum regime [3]. In our project, we show levitation of micrometer-sized superconducting particles by using a chip-based magnetic trap architecture that generates a quadrupole-like magnetic field of tunable strength[4]. The chip-trap has a multi-winding superconducting Niobium coils on two separate chips, which are stacked vertically. We have achieved levitation of 50 micron lead spheres below 50 mK using a current large enough to generate a strong magnetic lift force. Experiments are underway to read out the COM motion using a SQUID, which will facilitate feedback cooling in order to reduce the phonon occupation of the COM motion. The latter is a requirement for future quantum control of particle motion by coupling to superconducting circuits. Ultimately, this coupling allows generation of quantum states of the COM motion, such as superposition or squeezed states, which are a crucial resource for quantum sensing experiments aiming at measuring minute forces, e.g., gravity.[1] Romero-Isart, O., et al., Phys.
