Online Seminar: Quantum Computing with High-Dimensional Nuclear Spins in Silicon

Details

Bosonic logical encoding in the infinite-dimensional Hilbert space of quantum optics and cQEDs has grown into an exciting field of theoretical and experimental effort. It was recently proposed that similar principles can be applied to the — not infinite, but large — Hilbert space of single-object quantum systems, known as qudits. In this seminar, we will present recent research from Prof. Andrea Morello’s lab at UNSW Sydney, on the creation and manipulation of Schrödinger cat states in a single I = 7/2 123Sb nuclear spin qudit in silicon. We will also show how error-free virtual-SNAP gates can be implemented through software only. The high-fidelity logical operation of this powerful qudit platform will enable innovative new experiments in quantum information processing and quantum error correction within a scalable, manufacturable semiconductor platform (arXiv:2405.15494v1).
