Neutral Atoms: The Scalable Future of Quantum Computing Beyond Superconductors Quantum computing has long promised to revolutionize fields from drug discovery to cryptography, but scaling beyond noisy intermediate-scale quantum (NISQ) devices remains a monumental challenge. Google Quantum AI’s recent expansion into neutral atom quantum computing—using individual atoms as qubits alongside their established superconducting systems—marks a pivotal shift toward more scalable architectures. This approach leverages “nature’s perfect qubits”: identical atoms trapped by lasers, offering longer coherence times, room-temperature operation, and efficient error management without the cryogenic burdens of other platforms.[1][2] ...
