Founded in 2016, QDevil is an international quantum technology company focused on developing and manufacturing auxiliary electronics and specialized components, operating from mK to room temperature. The mission is to accelerate research and development in quantum electronics labs. To fulfill the mission QDevil helps customers around the world by supplying world-class auxiliary electronics.

Our scientists develop products specialized for quantum physics, and the product development is executed in close collaboration with researchers from several universities and research labs worldwide including the Center for Quantum Devices at the Niels Bohr Institute (at the University of Copenhagen). 

QDevil’s first product, the QFilter, was based on research cooperation between Harvard University and the University of Copenhagen. The product is already well described in the literature and has been sold to customers, including tech giants, in more than 20 countries.

The QFilter that so far is the dominant commercial cryogenic filter for reducing electron temperatures below 100 mK is now just one out of several products that have been introduced. The product portfolio additionally includes the QDAC, a 24-channel ultra-stable low noise DAC, the QBoard, a fast-exchange chip carrier system, and the QBox, a 24-channel breakout box.

QDevil is headquartered in Copenhagen, Denmark, and has recently established the subsidiary QDevil Inc. in the United States.
