Imagine every person on Earth holding a compass. 8 billion people, 8 billion tiny readings of the Earth's magnetic field. Together, they would draw the most detailed magnetic map of the planet ever made. Now shrink that idea down. Onto a diamond no bigger than a couple of square millimetres, we pack nearly nine times that many compasses, about 𝟳𝟬 𝗯𝗶𝗹𝗹𝗶𝗼𝗻 of them. That's the sensor inside our quantum diamond microscope 🧭 Each of these 𝗡𝗩 𝗰𝗲𝗻𝘁𝗲𝗿𝘀 is an atomic defect in the crystal lattice, where a nitrogen atom sits alongside a neighboring vacancy in the carbon lattice. And each one behaves like a microscopic compass needle, exquisitely sensitive to magnetic fields. When a chip carrying tiny currents is placed beneath the sensor, every one of these needles reacts to the resulting magnetic field, revealing both direction and strength through its fluorescence. With this collective "pointing," we reconstruct a high-resolution, three-dimensional image of the current flows inside the device. 𝗡𝗼𝗻-𝗱𝗲𝘀𝘁𝗿𝘂𝗰𝘁𝗶𝘃𝗲𝗹𝘆, 𝗮𝗻𝗱 𝗱𝗲𝗲𝗽 𝗶𝗻𝘁𝗼 𝗼𝗽𝘁𝗶𝗰𝗮𝗹𝗹𝘆 𝗼𝗽𝗮𝗾𝘂𝗲 𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲𝘀. That is precisely what makes the difference in modern 2.5D and 3D advanced packaging. Where conventional methods hit their limits as layer stacks on layer, our 70 billion sensors keep watching.
