Quantum Catalyzer is a Maryland-based startup studio that commercializes quantum sensing and imaging technologies. It develops tools like the Quantum Diamond Microscope (QDM) using nitrogen-vacancy (NV) centers in diamond for wide-field magnetic imaging. Applications target life sciences, materials science, and electronics industries. The studio drives portfolio companies including QDM.IO, which provides QDM systems, and EuQlid, focused on quantum microscopy solutions. Founded by quantum physicists from University of Maryland and Harvard, it translates academic research into commercial products. Operations are centered in the U.S. East Coast quantum hub.
