What is Quantum?

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.

Is quantum advantage moving too fast for you to keep up?

– An overview of the recent developments in quantum computing –

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 [1]. 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?”

How quantum physics may save Earth from global warming

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.
