QSI UTS Online Seminar: Coherent electrical control of a high spin nucleus in silicon – Dr Vincent Mourik, CQC2T

TITLE: Coherent electrical control of a high spin nucleus in silicon

SPEAKER: Dr Vincent Mourik

AFFILIATION: Fundamental Quantum Technologies Laboratory & Centre for Quantum Computation and Communication Technology, UNSW, Sydney

HOSTED BY: Dr JP Dehollain, UTS Centre for Quantum Software and Information

ABSTRACT: Nuclear electric resonance (NER) enables transitions of a high spin nucleus by modulating its electrical quadrupole interaction with an electric field. In this talk I will show how we found this effect in our single 123-Sb donor device in silicon, with a nuclear spin of size 7/2. We demonstrate, for the first time, coherent, purely electrical control of a single high spin nucleus. I will share our theoretical understanding of the microscopic mechanism at play in our device. Finally, I will discuss future research directions exploiting this versatile system.
