High - Dimensional Nuclear Spins in Silicon
Our group has recently demonstrated successful fabrication and full control of a 7/2 nuclear spin in a single antimony donor in silicon.
High-dimensional quantum systems present efficient, compact, and robust schemes for error correction and logical encoding in quantum information processing [, ]. Our group has recently demonstrated successful fabrication and full control of a 7/2 nuclear spin in a single antimony donor in silicon , leveraging the established infrastructure and fabrication strategies from phosphorus qubits. This advancement opens new avenues for qudit research, which we are actively exploring.
The 123Sb system offers a variety of control protocols, including conventional magnetic resonance (NMR) and nuclear electric resonance (NER), the latter of which we first experimentally demonstrated in 2020 . Through the development of complex phase-coherent control schemes, we have created logical states such as Schrödinger cat states and performed logical operations on a single antimony donor . This sophisticated control of a high-dimensional Hilbert space paves the way for exciting research in fault-tolerant quantum computing, including logical encoding, universal logical operations, syndrome detection, and error correction.
