Bringing quantum time into the lab—a single clock can run young and old at once
Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum physics, this relativistic ...
