A tiny defect in a diamond has been taught to store a quantum state like a spinning top that whirls for 11.2 seconds despite jolts. The secret is pure carbon without magnetic impurities and electronic noise compensation. This brings the quantum internet closer.
🎯 In 11.2 seconds, light travels 3.36 million kilometers—a distance equal to eight round trips to the Moon.
🎬 Diamond spins in a quantum network are a step toward 'ansibles' from science fiction—devices for instantaneous communication via entanglement.
