Ask me anything: Kiefer Vermeulen – ‘We had to figure everything out on a shoestring budget and on a really challenging timescale’

(Courtesy: Martijn van Leuven) Kiefer Vermeulen studied applied physics at Delft University of Technology in the Netherlands, where he did his master’s thesis at its QuTech research institute on the topological properties of Majorana quantum bits. He is now head of research at Delft Circuits, where he leads a team of quantum engineers developing the cabling and wiring needed for quantum-based devices. What skills do you use every day in your job? When I was at QuTech, I’d work on qubit systems using equipment that was sometimes worth several hundreds of millions of dollars. It’s now very different at Delft Circuits, which is a start-up company, where I have to get by with budgets that may be as little as few hundred dollars. So I need to take problems and condense them down into manageable work packages. After being a junior and then senior researcher at the company, I now lead a team of eight fantastic scientists and one of the most important skills for me is talking. I don’t just mean chatting – but really trying to figure out a problem by talking and listening to different stakeholders. It’s vital to be able to communicate what might be a very niche understanding of a specific field to a wider audience If you’re in academia and want to go into industry, it’s vital to be able to communicate what might be a very niche understanding of a specific field to a wider audience. If you can do that, then you can solve problems, which is what being in industry is all about. What do you like best and least about your job? I really like innovation. For anyone in industry, the aim is to make money, which means developing and selling products.

At Delft Circuits, we make cryogenic cabling for quantum computing, but none of that technology previously existed. We had to do it all ourselves – figuring everything out on a shoestring budget and on a really challenging timescale. That to me is super exciting especially when you’re doing something for the first time ever. As for the least favourite part of the job, raising money – whether it’s to build a lab or a factory – is tough. I’m currently in Denver, I was in Taiwan a few weeks ago, I’ve got three or four meetings coming up elsewhere in the next few weeks because the speed at which you need to do things might even outpace the money you can get for selling the things you have. I also don’t like the sheer amount of e-mails I have to deal with. When I started at Delft Circuits, there were just four members of staff. But now we’re so much bigger, I might get 50 or 100 e-mails a day. I guess I could speed things up by feeding them all into AI but I can’t really do that as a lot of work is confidential. What do you know today that you wish you knew when you were starting out in your career? I wish I’d known how important communication is, whether that’s getting your ideas across – or understanding those of other people – and really being able to frame your expertise and explain it to potentially non-technical people. Trust is important too because in start-up companies you all need to rely on each other and work through problems together so that things come to fruition. I also wish I’d known to talk a bit less – and let the other person in a conversation come up with the answers that might be different to your own. When I started out, I always wanted to answer problems quickly – in fact, I had to do that because it was expected of me. But as I’ve started managing and leading teams, I’ve learned to give others the opportunity to go through the same type of brain puzzles and thinking that I went through myself. Want to read more?
