A new method to measure fabrication induced surface spin densities

This project aims to detect very low surface densities of unwanted electron spins on the surfaces of quantum computation devices. For many applications in quantum computation, electron spins that reside on device surfaces limit the coherence times of their qubits. By polarizing these electron spins at cryogenic temperatures with the moderate magnetic fields provided by a magnetically tipped force sensor, it is possible to detect very low spin densities by a force microscopy technique called magnetic resonance force microscopy (MRFM). We seek support to further develop a much simplified version of this experiment, called the easyMRFM, to facilitate the needs of the growing international community of quantum computation devices.
