Qblox: The future of controlling quantum computers

By Tessa van Breeden - Most computers are efficient enough for daily activities like emailing, gaming, or browsing the net. But in many more demanding applications, the greater the computing power, the better.

This is where quantum technology comes in with its potential to speed up discoveries and innovations, such as drug development to cure diseases, speeding up AI and ML models, climate models, and other complex problems.

Qblox enables scientists and industry partners to speed up their calculations worldwide with scalable, low-latency qubit control equipment. In 2023, it won the Scaleup of the Year award at YES!Delft. Let’s take a look at their journey and future plans.

From quantum physics to quantum technology

Co-founders Niels Bultink and Jules van Oven embarked on their entrepreneurial journey five years ago. Having previously worked at a startup, Niels pursued a PhD program to develop small prototype quantum computers at TU Delft. With the help of engineers at the University and TNO, they established Qblox, which specializes in quantum chip control and aspires to become the world’s leading company in this field.

Controlling quantum chips

Qblox’s unique value proposition lies in its laser focus on one element of the quantum computer, namely control electronics. This combination of hardware and software enables researchers and industry to control quantum chips. While larger companies may also have projects in quantum technology control, Qblox aims to establish itself as the expert in the field. Additionally, their modular solution provides customers with easy customization for each type of qubit technology and allows for easy scalability.

We are very good at accelerating the applications and impact that quantum technology can bring us. We are an enabler for the quantum technology field.Niels Bultink, CEO and co-founder of Qblox

Quantum is the future

Some might feel quantum technology is still futuristic, but Qblox aims to change that perspective. It is why they built a quantum computer from scratch at an international conference. By building a quantum computer in just a few days, they wanted to show that quantum technology is not just an experiment in a scientific laboratory but something that can be already built and used in a few days.

We have around 100 customers worldwide. We’re very proud of being part of the Barcelone Supercomputer Centre. Our control stack is used in their quantum computer. We also have collaborations with the leading universities, like Yale, Chalmers, and, of course, the TU Delft.Niels Bultink, CEO and co-founder of Qblox

Doubling in size twice

Of course, they took many steps to get where they are today, with over a hundred customers. For example, they participated in the YES!Delft Accelerator program in 2019. Since then, they have doubled in size, all while being entirely bootstrapped. Niels emphasizes that bootstrapping was never a fundamental choice but that it fit with their situation over the years. Next year, Qblox aims to double in size again. They will focus more on industrial customers and try to promote their quantum technology internationally. For example, they are setting up several subsidiaries to accelerate their internationalization plans.

The YES!Delft program is very valuable because it enables startups to interact closely with founders and build a network of advisors, coaches, and partner. Niels Bultink, CEO and co-founder of Qblox
