Abstract
In a device comprising two double quantum dots separated by a 250-μm-long superconducting resonator, virtual photons in the resonator are shown to mediate the coupling of electron spins between the quantum dots. When the spin–spin coupling is activated for a controlled duration, oscillations between the spins are observed.
期刊介绍：
Nature Physics is dedicated to publishing top-tier original research in physics with a fair and rigorous review process. It provides high visibility and access to a broad readership, maintaining high standards in copy editing and production, ensuring rapid publication, and maintaining independence from academic societies and other vested interests.
The journal presents two main research paper formats: Letters and Articles. Alongside primary research, Nature Physics serves as a central source for valuable information within the physics community through Review Articles, News & Views, Research Highlights covering crucial developments across the physics literature, Commentaries, Book Reviews, and Correspondence.
