Chip-based superconducting traps for levitation of micrometer-sized particles in the Meissner state

Funding

We acknowledge fruitful discussions with Jordi Prat Camps, Prasanna Venkatesh and COMSOL support. We thank Carles Navau and lvar Sanchez for a critical reading of the manuscript. We are thankful for initial support in microfabrication from David Niepce. The work was supported by Chalmers' Excellence Initiative Nano and the Knut and Alice Wallenberg Foundation through the Wallenberg Center for Quantum Technology (WACQT) and the Wallenberg Academy Fellow. 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 C3SE, Chalmers, partially funded by the Swedish Research Council through grant agreement no. 2016-07213.
