What to know about Institutional Prestige (VCU)

Researchers at Virginia Commonwealth University have developed a method using nanomagnets and acoustic waves to control the spin of electrons in diamond-based qubits. This technique aims to reduce the physical space required for qubits, potentially making quantum hardware more scalable and energy-efficient.

What happened

Nanomagnets control diamond qubits, pointing to more scalable quantum hardware Gaby Clark Scientific Editor Robert Egan Associate Editor Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but…

Why it matters

New research from Virginia Commonwealth University brings scientists one small step closer to quantum computing at a practical scale, which could help dramatically reduce energy usage and computing times in some industries.

Common ground

In the study, recently published in Nature Communications, the researchers used minuscule magnets—twice as small as the wavelength of light—to create the building blocks of quantum computing, pioneering a technique that could decrease the physical space…
