You might not know that you use quantum technologies every day pretty much constantly. Here I have summarised five of them, but there are many others. Quantum physics is often seen as a weird part of physics, far removed from our every day lives but this couldn’t be further from the truth. The entire modern world exists because of our understanding of quantum physics!
