Laser-cooled helium-3 atoms as qubits held within optical tweezers overcome decoherence, for scalable neutral-atom quantum processors

"helium quantum tunneling rates at least 3X faster/ clearer energy structure, than lithium-based... leverages helium’s unique 2-hour metastable state, acting as energy stepping stone making trapping high-energy atoms feasible... helium-3 is fermionic, avoiding many of the quantum errors inherent to bosonic systems and simplifies fermionic quantum computing... future: build the physical device by first validating the trapping mechanisms with helium-4 before transitioning to helium-3"
