Can particles really be in two places at once? Featuring @ArvinAsh

Today I tell you what happened when I wrote an opinion piece for the Guardian about quantum computing, had to explain what a qubit is, and decided against using the phrase that it “can be in two states at the same time”. What happened next and what did I learn from it? Can two particles really be in two places at once? What does that even mean? @ArvinAsh and I try to sort it out for you. The opinion piece I am referring to is here: https://www.theguardian.com/technology/2019/aug/02/quantum-supremacy-computers You can support me on Patreon: https://www.patreon.com/Sabine I now have a newsletter with weekly science updates!
