# Quantum logic operations and algorithms in a single 25-level atomic qudit

**[Nature](https://daily.dev/sources/nature)** · 3 min read · 0 upvotes · 0 comments

## Summary

Researchers demonstrate a 25-level quantum system (qudit) using a single trapped barium-137 ion, achieving high-fidelity state preparation and readout across all 25 internal levels. The study investigates how errors scale with qudit dimensionality, identifies primary error sources affecting quantum coherence, and implements a 3-qubit Bernstein-Vazirani algorithm and a 4-qubit Toffoli gate using just one trapped ion. The findings suggest that large-dimensional qudit architectures offer a promising path toward more hardware-efficient quantum computing.
