ALT Brightly-colored lines with sharp kinks. Colors include golds, magenta, blues and teal. A zoom-in panel demonstrating the small scale complexity in high-resolution simulations of a slice of 3D simulations of cosmic rays. Colors show the electric current’s magnitude.

ALT Large circle with network of smaller circles colored white, gold and blue linked by lines. Caption: A schematic of a quantum circuit used to study quantum gravity. A one-dimensional magnet enters the circuit at the circle’s circumference and a model of gravity is produced at the black dots. The blue, white, and yellow circles represent the quantum gates making up the circuit. (Image: Rahul Sahay, Mikhail D. Lukin, Jordan Cotler, arXiv:2401.13595.)
