Coherent electric field manipulation of nuclear spin qudit
Sumin Lim, Mikhail V. Vaganov, Niccolo Fontana +2
The authors demonstrate coherent electric-field manipulation of an I=5/2 nuclear spin qudit in Mn2+-doped ZnO, using hyperfine-coupled electron spins to achieve resonant and non‑re…
Fault-Tolerant Encoding of Logical Qudits in Spin Systems
Sumin Lim
Universal quantum computers require fault-tolerant logical qudits, as qudits naturally align with the simulation of multi-level physical systems. Here, we present a general framewo…
Designing quantum error correction codes for practical spin qudit
Sumin Lim, Arzhang Ardavan
The implementation of practical error correction protocols is essential for deployment of quantum information technologies. Ways of exploiting high-spin nuclei, which have multi-le…
Demonstrating experimentally the encoding and dynamics of an error-correctable logical qubit on a hyperfine-coupled nuclear spin qudit
Sumin Lim, Mikhail V. Vaganov, Junjie Liu +1
The realization of effective quantum error correction protocols remains a central challenge in the development of scalable quantum computers. Employing high-dimensional quantum sys…
