5 Companies From Denmark Contributing To Quantum Tech’s Future

Serious Work

Nobody would be surprised to know that Denmark — along with Finland — is a proud hub of frenetic quantum activity in the commercial space. Known for their progressiveness and tech-savvy attitude, the Danes are some of the most innovative on the continent with the Technical University of Denmark (DTU) and the University of Copenhagen leading the charge for universities, while academic centres and groups like the Center For Macroscopic Quantum States, the Center For Quantum Devices and the Quantum Optics Center are doing some serious work in their own respective fields in quantum.

If you want to learn more, we’ve compiled the most comprehensive list of the top quantum computing companies available!

Now, it’s time to look at five commercial enterprises doing some clever things in quantum tech in the country. Once again, The Quantum Insider’s very own proprietary data platform was used in the main as a source.

1. Hafnium Labs

Hafnium Labs


Based in the country’s capital city, Copenhagen, Hafnium Labs leverages multiple tools including quantum technology to support molecular discovery.

Founded in 2018 by Jon Christensen and Bjørn Maribo-Mogensen, Hafnium Labs has developed a breakthrough system for combining state-of-the-art predictive methods, such as quantum chemistry and AI, with experimental physical property data.

By intelligently and transparently using all available information, it provides the most accurate physical property predictions and quantifies the uncertainty, so you know how reliable each prediction is.​

Its Q-props™ tools support decision-making from molecular discovery to process optimization.

2. Molecular Quantum Solutions

Molecular Quantum Solutions

Like Hafnium, Molecular Quantum Solutions (MQS) is another Copenhagen-based quantum company. Providing computational tools to accelerate research and development efforts by the pharma, biotech and chemical industry, its tools make use of super- and quantum-computers with computational models and algorithms to calculate the properties of materials and chemicals in a fast and efficient way.

Users are able to screen for example new materials for batteries, green solvents, new drugs and bio-degradable plastics instead of conducting costly experiments in the laboratory.

Molecular Quantum Solutions was founded by Mark Nicholas Jones and Łukasz Ruszczyńskiin in 2019.

3. NKT Photonics

NKT Photonics


Nordiske Kabel og Traadfabriker (today NKT Photonics) was founded in 1891 and has been a listed company since 1898. Over the next 90 years, the company grew into one of Denmark’s foremost industrial enterprises, with a focus on cable production (electricity, power and telecommunication cables), but also active in the production of nails, screws and other hardware for the Danish market. In 2009, Crystal Fibre — the largest commercial supplier of microstructured specialty fibre and Koheras — the leading company within low noise lasers and SuperK supercontinuum white light lasers — merged, becoming NKT Photonics.

NKT Photonics has lasers in space and deep under the oceans and its products run in both clean rooms and on oil rigs at sea. The company seeds the World’s largest laser fusion experiment and power hundreds of the most advanced microscopes on the Globe, aiming to make a difference in the World and we are involved in projects that will transform the way we live.

NKT Photonics is the leading supplier of high-performance fibre lasers, fibre optic sensing systems, and photonic crystal fibres. Its main markets are Medical and Life Science, Industrial, Aerospace and Defense, and Quantum and Nano Technology.

4. Sparrow Quantum Aps

Sparrow Quantum Aps


Sparrow Quantum Aps was founded in 2015 by Peter Lodahl. A privately held company with headquarters in Copenhagen, the startup develops and commercializes photonic quantum technology components based on research and patents developed in the Niels Bohr Institute Quantum Photonics Lab.

Sparrow provides photonic quantum components, namely an integrated chip for on-demand highly coherent single-photon streams, that is made from ultra-precise InAs/GaAs quantum dot structures embedded in photonic crystal waveguides.

The 3mmx3mm chip is sectioned into an array of structures engineered for emitting single photons at specific wavelengths ranging from 920nm to 980nm.

5. QDevil (acquired by Quantum Machines)

QDevil (acquired by Quantum Machines)


Acquired by Israeli company Quantum Machines last month, QDevil was founded in 2016 by Jonatan Kutchinsky and Ferdinand Kuemmeth. An international quantum technology company focused on developing and manufacturing auxiliary electronics and specialized components, operating from mK to room temperature, its 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.

QDevil’s scientists develop products specialized in 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 is so far the dominant commercial cryogenic filter for reducing electron temperatures below 100 mK and 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 established the subsidiary QDevil Inc. in the United States.
