For as long as computers have existed, physicists have used them as tools to understand, predict and model the natural world. Computing experts, for their part, have used advances in physics to develop machines that are faster, smarter and more ubiquitous than ever. This collection celebrates the latest phase in this symbiotic relationship, as the rise of artificial intelligence and quantum computing opens up new possibilities in basic and applied research
