A glowing spot on a crystal is like a firefly that you can wake not only with a flashlight but also with the warmth of your palm. Such spots, single-photon sources, can emit light one particle at a time, which is essential for quantum communication and computing.

A quantum computer based on neutral atoms is like a city where couriers, laser tweezers, physically carry packages between addresses. While one courier drags an atom across the entire chip, the others sit idle. This is slow and error-prone. The new architecture replaces couriers with a shared radio wave.
