Welcome to the QuTech blog!

Writing a blog post about quantum information and taking a picture of a rapidly approaching wave are almost equally ephemeral – a fleeting impression of an exciting development that has long moved onwards once the ink is dry. In the past two years, QuTech has grown to over 140 people working towards a quantum computer and quantum internet – or if you put the two together, a quantum cloud. We have celebrated scientific successes such as the first loophole free Bell test, and seen significant developments when Intel decided to enter the quantum domain, joining Microsoft as an industrial partner of QuTech.

More interesting, however, is undoubtedly the road ahead. Evidently, it is an intriguing prospect that already relatively few qubit quantum computing devices may solve useful problems faster than any classical machine. For us in the field, however, they would also invariably transform the landscape of quantum technology research we are accustomed to – both for theoretical and experimental research. An availability of few qubit devices promises the novel opportunity to develop new applications and algorithms by a heuristic approach often taken in classical computing – simply because we all have a classical computer on our desk to try them out. From an experimental perspective, we may see a divergence of experiments that aim to probe physics but work with only a handful of qubits, and the more engineering oriented aspect of designing larger scale computing technology. All the while, quantum information has made a sweeping entrance into many other areas of physics – offering the perspective of information as a powerful new way to decipher nature.

To advance quantum technologies, the European commission has recently established a 1bn euro flagship. Whether intentionally or not, the video provided for the flagship highlights the situation our field may find itself in. Feeling the rapidly approaching wave the question will be whether we do – as the surfer – fully commit to these possibilities by taking the chance to pop up on the surfboard. Or, whether we will keep hanging onto the well accustomed board and thus invariably wipe out. Success in quantum technologies does indeed require all the commitment we can muster, since realizing a quantum computer is incredibly challenging. Only time will tell whether we will be able to overcome all obstacles, but as with all great endeavours the only path lies forward.

Initiated by our excellent blog editorial team, we hope this blog may allow you to take part in some of these exciting developments. Written by all members of QuTech, it will feature a diverse set of posts ranging from ongoing research, people at QuTech, to – hopefully – easier explanations of what all this quantum stuff is actually about.

Sometimes, the blog may also give you a glimpse into what these scientists – like the theorist and experimentalist pictured here – are up to all day.

See you soon at the QuTech Blog. Enjoy!

About Us

Welcome to ‘Bits Of Quantum’, the official blog by QuTech! QuTech is an academic research institution that houses many scientists who spend a large part of their time doing mathematics, experiments, and a lot of quantum mechanics. We would like to share bits of our quantum research with you, and give you a taste of what life in a large research institute is like. To that end we, four PhD students from different parts of QuTech, started the blog you are looking at right now. As the editorial team we are very excited about channeling all the stories that can be told by and about QuTech and quantum technologies. Thank you for reading this blog and we hope you enjoy reading the many posts to come!


The editorial team,
Jonas, James, Adriaan and Suzanne

JonasHelsenJonas Helsen – Hey! My name is Jonas and I am one of the theorists at QuTech. I only started my PhD a year ago so I still have lots to learn but I’m really excited about being here! I’m also passionate about teaching people about the magical world of quantum computing which is why I co-started Bits Of Quantum with my lovely co-editors! Happy reading!

JamesKrollJames Kroll – I am James, an experimental physicist hailing from Scotland. I work in the topological quantum computing roadmap of Leo Kouwenhoven, as it requires an exciting mix of condensed matter physics theory, experimental cryogenics, electrical engineering and computer programming – all things that I somehow enjoy. If I’m not in the lab, you will most likely find me cycling somewhere or reading. Or eating. That’s a pretty important part of my life.

Adriaan Rol AdriaanRol – Hi, I am Adriaan, an experimentalist in Leo DiCarlo’s group where we are working on a quantum computer based on superconducting transmon qubits.
I really enjoy trying to find the (abstract) essence of things while at the same time being able to experimentally test if my ideas actually work.
Whenever I’m not in the lab you’ll probably find me on the water or enjoying an overpriced coffee at my favourite coffee place.

Suzanne van DamSuzannevanDam – My name is Suzanne, and I am doing a PhD in the lab of Ronald Hanson, since two years now. One of my favourite things is to see the quantum world in the lab on a daily basis. My hope is that from this blog it will become clear why I am so excited about this!
