They are the "heart" of every electronic device, from laptops to electric toothbrushes: printed circuit boards, also known as PCBs. These rigid boards are covered with copper traces and soldered ...

The idea proposed by the team involves creating what they describe as a temporal circuit board—it would be made using ultracold atoms that move around in repeating patterns similar in form to those ...
