Quantum Computing & Tech ⚛️ on Instagram: "This is not CGI. It’s a single atom. Captured by physicist David Nadlinger, this image shows one strontium atom suspended between two electrodes, held in place by electromagnetic fields inside a vacuum chamber. When blasted with precision lasers, the atom absorbs and re-emits light so strongly that it becomes visible to the naked eye. A fundamental building block of reality, isolated and glowing.
