John Martinis gestures in front of a slide entitled "Quantum's scaling revolution" showing a Google dilution fridge and comparing it with a snarl of wires in a photo of a 1960s computer

Michel Devoret standing in front of a slide listing "What can you do with artificial atoms that you cannot do with natural atoms (yet)?" The list includes "measure the traversal time of tunneling", "prepare Schroedinger cat state living in two boxes", "observe the finite duration of quantum jumps and reverse them", "perform random circuit sampling beyond classical regime", "correct logical qubit memory beyond break-even", "employ as detectors to perform NMR experiments on single nuclei" and "run verifiable quantum echoes algorithm with practical advantage"
Michel Devoret standing in front of a slide entitled "From macroscopic quantum phenomena to superconducting artificial atoms". There's a cartoon of a person in an auto mechanic shop saying "Actually I started in quantum mechanics but somewhere along the way I took a wrong turn."

A video showing how melted metal nanoparticles behave when heated on a "hob" of graphene. The nanoparticles are represented by a hexagon full of coloured blobs and the graphene by a hexagonal grid. At the start of the video, all the blobs are blue (cold). As the video progresses, the blobs within the hexagon turn warmer colours and vibrate wildly, while the blobs at the edge of the hexagon remain blue and stationary.

Screenshot of an article on the Physics World website. The screenshot shows the headline ("New analysis of M67 cluster helps decode the sound of stars"), a bright yellow image of acoustic waves in the interior of a star and a series of sharing buttons, including the Bluesky butterfly, which is ringed in red
Photo of the BASE-STEP system sitting on a bright yellow trolley after being unloaded from the transport crane, which is visible above it. A woman in a hard hat and head scarf watches from the ground, while a man in a hard hat stands above her on a set of steps, also watching. (Photo: BASE/Maria Latacz)
Artist's impression of what an aurora would look like on Mars. The starry sky is greenish and blueish and the Mars rover Perseverance appears, dimly lit, in the foreground
