6.648 billion people around the world use smartphones, devices that only function due to the mind-boggling laws of quantum mechanics. Beyoncé Knowles, on the other hand, “only” has 273 million followers on Instagram – although it is somewhat like comparing apples to oranges, the claim that quantum technologies are more popular than Beyoncé is true.


FIGURE 1. Participants of the 5th Solvay Conference. This picture holds the record for capturing the most Nobel Prize winners at once – 16 of the 29 people in the photo have won the award. Marie Curie won two, yielding a total of 17 Nobel Prizes in the photo.

Another fact about quantum technology is that its principles were well known to mankind even before we knew how to produce film-based colour photography, as the below example photo from 1927 impressively shows (Brussels, 5th Solvay Conference on “Electrons et Photons). Already at this time, the quantum pioneers (Curie, Einstein, Schrödinger, …) vividly discussed the physical principles of quantum technologies.

So, what is all the fuss about the current quantum hype? We are dealing with century-old technology, right? The answer to this question is very common in the field of quantum tech, “Yes and no”.

Although quantum mechanics have been well known for a long time, their transfer into real-world applications like transistors, lasers and the resulting computers, smartphones, GPS navigation, etc. was a slow process. None of the pioneers could have ever imagined the technological potential. That, for example, a child living in Europe could call their grandmother living in Australia in real-time, using a hand-held device. 


FIGURE 2. Nerdy joke about Schrödinger's cat – Erwin Schrödinger (top) proposed a thought experiment where a cat (bottom) is placed in a box together with a poison flask that shatters when a radioactive atom decays. Since these atoms have a quantum state between “decayed” and “non-decayed” before they are actually being measured, Schrödinger claimed that as long as nobody opens the box, the cat is in a state of “dead and alive”.

In the last years, quantum technologies have been developed up to a point where it is now possible to control and manipulate single quantum states, rather than ensembles of a multitude of quanta. This opens a world of new effects and applications and is referred to as the “Second Quantum Revolution”. New possibilities emerge in the fields of quantum computing, quantum sensing and quantum communications. Successful industrialisation-enabling technologies such as photonics, cryogenics, semi-colour tech, vacuum tech, diamond tech and more. There are also other key aspects such as miniaturisation and robustness that need to be addressed.

I have a background in nanostructure engineering and physics. My academic focus areas were photonic crystals - and crystal fibers, optical tweezers, and nanoanalytics and patterning. I spent 8 years in industry in various roles and coordinated the international congress "Applied Industrial Optics" for OPTICA (former Optical Society of America) as General Chair for several years. At EurA AG, I am Team Leader Analytics and Sensors and have extensive experience in managing large projects. I lead the quantum photonics network and coordinate activities in quantum technologies for EurA.
