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? @Arvin Ash and I try to sort it out for you.

The opinion piece I am referring to is here: https://www.theguardian.com/te....chnology/2019/aug/02
