Google was looking to tell the world about its Quantum AI Lab, and get more middle-school-aged kids excited about science and engineering. So we figured we’d reach those kids where they already are: Minecraft. We built qCraft, a mod that introduces quantum physics into Minecraft, letting anybody experiment with quantum entanglement and superposition. In what was probably the best writing assignment ever, I wrote videos explaining how qCraft works, built the scenery for the videos in Minecraft, then shot and narrated them myself (that’s my voice in the video above). Then we set up a giant, shiny booth at Minecon, the official Minecraft convention, and spent two days telling twelve year-olds how cool quantum physics is.
