"neutral-atom quantum computers often rely on exciting atoms into Rydberg states easily disrupted by environmental noise, overcome using lithium-6 fermion atoms operating through atoms' wave function overlap... Max Planck Institute 99.75% peak accuracy controlling potential barriers between neighboring atoms using high-stability lattice/ quantum gas microscope monitoring individual atoms. ETH Zurich 99.91% accuracy across 17K atom pairs utilizing bias voltage tuning coupling strength between atoms"
