Creo que tal vez para el primer artículo debimos haber empezado con una cita elegante de algún poeta o científico, dicha hace mucho tiempo y que sea vigente aún. Pero no lo vamos a hacer. En lugar de eso, empecemos con un pequeño experimento. Llená una taza de algún líquido. No, no café. Ya sé que estabas pensando en eso. Es mejor algo más claro, más transparente. Tenés que poder ver a través del fluido. Necesitás también algo que flote homogéneamente en el líquido, como semillas de chía cuando se ponen suavecitas, o esa bebida de aloe que venden ahora en los supermercados. Ese último es lo mejor que he encontrado para este experimento.
A friend of mine recently suggested a documentary to me about the mind’s healing power. Terrible pseudoscience all around, but it landed some nice points about stress. Nevertheless, I was horrified at how easy the word quantum was dropped, without any context, and any reason. And this is not an isolated event, I have seen this trend for some time. And I think that is not only a trend in the circles of pseudoscience. In science-fiction and superhero movies for instance, quantum jargon is used as mumbojumbo and plot devices, admittedly a whole more harmless way. However, with buzzwords like quantum healing or quantum consciousness on the rise, we physicists must take a stand and clarify what does the word quantum really mean.

Vienna, 12th of October, 2019:
Eliud Kipchoge became the first human to run a sub 2-hour marathon. Once believed to be unattainable, his time, 1:59:40, will not be officially recognized as a world record . The reason for this is that the experiment to run 26.2 miles in under two hours was conducted under specific conditions which are not comparable to standard racing situations. Having an electric car and a team of 41 world-class runners in front of him, setting the pace, he broke “the last barrier of modern athletics”. Or to put it in his own words: “Vienna is about running and breaking history, like the first man on the moon.” Continue reading “Is quantum advantage moving too fast for you to keep up?”
I don’t think we have to tell you that the Universe is a very complex and huge place. But in case we actually do, here it is: the universe is bigger and more complex than the human mind can fathom. Think about our galaxy, with its millions of stars, which have their own solar systems with some planets and hundreds of asteroids and general debris. All of them attract each other gravitationally and modify the path that each other has, literally all the time! How can one even start to try to predict how the Universe works with such staggering number of bare elements?
Pictorial Quantum Simulation: Atoms are sitting in a lattice built up by standing light waves, ready to be used for studying the most intriguing questions of state of the art research.
cOOKING UP A qUANTUM sIMULATION
Supercomputers are cornerstones of modern industry. They help to design complicated objects like aircraft, provide the handling of big data sets in AI, trade shares at stock exchanges and set the standards for today’s encryption. However, there exist highly complex problems involving the smallest building blocks of our world which cannot be solved on these supercomputers yet. Continue reading “Quantum Simulation Cookbook”
Transporting renewable energy to where it’s needed lies at the heart of the human endeavour to get rid of the need for fossil fuels. Superconductors can do so without loosing any of the precious electricity on the way, seemingly defying physical intuition. Find out in this article why many body physics is needed to understand their counter-intuitive behaviour, what role quantum entanglement plays and how quantum computation might lead to the discovery of materials which may give us the tools for a greener future.Continue reading “How quantum physics may save Earth from global warming”
Things are about to get messy.
Give me a moment of your day, and let me put a picture in your mind. Imagine you and a friend each have a soup in a plate, and each soup has two carrot pieces, one potato and not so much broth in it. You are bored, it is a slow afternoon, so you decide to perform a little experiment.
How quantum technologies enable uncrackably secure communication.
In our modern computer world, being able to encrypt messages is not only necessary to keep some information secret from others, but is a key part of technologies such as cryptocurrencies like Bitcoin. Furthermore, the scandals around widespread eavesdropping of intelligence agencies has shown the world that in fact none of the routines used today are really secure. But what if I told you that in ten years all communication will be secure because it is physically impossible to eavesdrop on communication encrypted by quantum cryptography?
I remember the first time I saw a magnifying glass. I was absolutely fascinated by such an object. It allowed me to see so much more than I could normally (even then, when I could actually see something without glasses or contacts). It was the most amazing thing I had seen until then. Well, what was an amazing discovery for me, had been around for ages in human history. Lenses and objects which resemble magnifying glasses date back four thousand years! But of course, our curiosity is boundless, we humans always need more. I quickly found myself wanting to see even deeper into this weird, amplified creatures. Fortunately, humans didn’t wait a lot to yearn for better resolutions.
