Strong coupling and quantum Zeno dynamics can isolate and protect specific quantum states from decay.

Scientists can use a trick called quantum Zeno dynamics to build a protective fence around quantum information. By using strong laser couplings and frequent measurements, they can split a particle's potential states into separate groups. This forces the particle to stay within a safe zone. Instead of losing its delicate quantum features to the environment, the particle is locked into a smaller, controlled space where it can safely perform calculations without breaking down.
