Seminar: STM-engineered spin arrays for qubit control and Majorana bound states
- Speaker: Deung-Jang Choi, Ikerbasque Associate Professor at the Materials Physics Centre (MPC/CFM, UPV-CSIC), San Sebastián.
- Date: 26 March.
- Time: 12:30.
- Venue: Salón de Grados, Faculty of Sciences, University of Zaragoza.
Seminar Summary: In this talk, Dr Choi will present advancements in the deterministic control of matter at the atomic scale through the use of scanning tunnelling microscopy (STM). She will explain how this tool is utilised for both the fabrication and readout of spin arrays assembled with atomic precision, enabling the individual control of electron-spin qubits in solid-state systems.
Furthermore, she will explore the extension of this method to superconducting surfaces, where correlated interactions generate emergent quantum states, such as Majorana bound states. These findings are fundamental to the development of topological quantum computation and establish atomically engineered surface spins as a scalable platform for studying quantum phenomena and developing future quantum devices.
About the speaker: Deung-Jang Choi’s research focuses on harnessing the potential of surface-supported spins for quantum technologies. Her expertise spans the precision engineering of superconductor-supported magnetic systems and the cutting-edge application of time-dependent modes in scanning tunnelling microscopy.
This event is held in collaboration with INMA (CSIC-UNIZAR), the Department of Condensed Matter Physics, and the Faculty of Sciences at the University of Zaragoza.
