Clever New Experiment Looks for Quantum Jumps of Big Things

I got a lot of questions about an article which said that physicists have designed “a Way to Detect Quantum Behaviour in Large Objects, Like Us”. I had a look at the paper. It’s about what I consider without exaggeration the most important question in physics today, that is, why do we not observe quantum effects in everyday life. They want to figure out if macroscopic objects still make quantum jumps and have come up with a clever idea for that.
