Periodic Reporting for period 2 - LOQO-MOTIONS (Local quantum operations achieved through the motion of spins)
Reporting period: 2019-08-01 to 2021-01-31
The aim of LOQO-MOTIONS is to exploit the long coherence times observed in spins of atomic defects in materials and open up a new approach for coupling spins based on dipolar interactions combined with physical motion to achieve local quantum operations. This approach is inspired by a recent blueprint for the implementation of a surface code using donors in silicon, permitting fault- tolerant operation even with the limited positional accuracy of ion implantation. LOQO-MOTIONS assembles a comprehensive set of tools required to explore and exploit physically mobile spins, including: versatile single-donor spin measurement, coupling of donor spins and optically-addressable defect spins, and cryogenic scanning of probe spins over static spins to generate entanglement.
