Quantum Design International (QDI)

Quantum Design International (QDI) is a global manufacturer and distributor of scientific and industrial instrumentation, best known as a leading commercial source for automated materials characterization systems that combine cryogenics, superconducting magnets and precision measurements. Founded in 1982 and headquartered in San Diego, California, the company serves researchers in physics, chemistry, materials science, nanotechnology and related fields through a worldwide network of subsidiaries and partners across Europe, Asia and the Americas. Quantum Design’s platforms have become reference standards for magnetic and physical property measurements and are widely cited in the scientific literature.

For the spintronics community, Quantum Design provides the cryogenic, high‑field and precision measurement infrastructure that underpins much of today’s experimental work on spin‑based materials and devices. Its systems enable detailed studies of magnetotransport, magnetization dynamics and correlated phenomena in thin films, multilayers and nanostructures that form the basis of modern spintronic technologies. Through its distribution activities, QDI also partners with specialized tool makers in ion-beam engineering and magnetic characterization, further extending its relevance to spintronic device fabrication and tuning.

In 2026, Quantum Design expanded more directly into quantum and spin‑sensitive microscopy by acquiring Qnami, a Swiss pioneer in diamond NV‑center quantum sensing, and earlier that year it added Oxford Instruments’ NanoScience division to its portfolio. These moves strengthen the company’s capabilities in nanoscale magnetic imaging, nanomagnetism and quantum materials characterization, giving spintronics researchers integrated access to both cryogenic measurement platforms and advanced scanning probe tools within the same ecosystem.
