Non-invasive magnetic imaging and high-fidelity coherent control of surface spin qubits

Focus topic:	STEM

After finishing PhD on atomic-scale magnetism from EPFL, Switzerland, Dr. Aparajita Singha moved to the IBS centre for Quantum Nanoscience, South Korea for postdoctoral research. There she explored quantum sensing using a novel technique that combines electron spin resonance with scanning tunnelling microscopy. Since 2020, she has been leading the Quantum Sensing group at MPI-FKF.

Goals

The appeal of controlling individual atoms and molecules at their native spatio-temporal limit has driven both fundamental research and technological breakthroughs for decades.

The aim of the project is to manoeuvre quantum properties of such smallest building blocks of matter, especially by probing them in the least invasive manner. To achieve this goal, atomic force microscopy (AFM) with novel colour centre probes (NV) will be used. Combining the unique properties of the NV-sensors (unparalleled magnetic sensing capability, high-fidelity optical access, and broad operational range of temperature) Aparajita Singhas group aims to realize highly sensitive and non-invasive quantum control at the atomic/molecular scale.
