"longest measured lifetime for individual Rydberg atoms, largest controlled circular Rydberg atoms, longest optical-tweezer storage time for them... highly excited electrons forced into stable circular orbits >1,000X larger than standard atoms preserves quantum coherence far longer than free-space alternatives... at room temperature by using metal plate thermal radiation shielding... secure communications, simulators, fault-tolerant scalable computing hardware enabling longer computations/ vastly lower error rates"
