QuSpectra mark QuSpectra NASA Awardee
Portable quantum sensors

Molecular analysis,
anywhere.

We bring NMR capabilities into a portable format. No superconducting magnets, no liquid helium, no dedicated facility infrastructure.

Powered by diamond quantum sensors, QuSpectra delivers high-sensitivity molecular analysis from very small sample volumes.

How it works

From sample to fingerprint, in three steps.

The unique stack

We integrate quantum sensor and microfluidics in an unique stack. Changes in the magnetic field caused by the sample are sensed by the NV-centers in the diamond.

About us

QuSpectra is developing portable quantum sensing instruments based on nitrogen-vacancy (NV) centers in diamond. We are compressing laboratory-scale quantum sensing and spectroscopy systems into compact, board-level instruments that deliver high-performance measurements in a portable form factor. Our technology combines quantum sensors, photonics, microwave electronics, embedded systems, and microfluidics to enable next-generation analytical tools.
