# Tiny Carbon Rings Enable a New Form of Quantum Control

**[The Quantum Insider](https://daily.dev/sources/thequantuminsider)** · 3 min read · 0 upvotes · 0 comments

## Summary

Physicists at Martin Luther University Halle-Wittenberg used computer simulations to show that carbon nanotori — ring-shaped carbon nanostructures — can generate and control toroidal moments without energy loss at the nanoscale. When a constant electric field is applied, electrons form a 3D vortex, creating a toroidal dipole. This third class of electromagnetic dipole, previously difficult to replicate at the molecular level, could enable more precise control of superconductors in quantum computing systems, reducing signal noise and energy consumption by directly altering quantum mechanical phases rather than relying on hard-to-focus magnetic or electric fields.
