Caltech physicists created the largest qubit array ever assembled: 6,100 neutral-atom qubits trapped in optical tweezers. This shatters the previous record and demonstrates the scaling potential of neutral-atom platforms. While not yet a full gate-based quantum computer, this array proves that neutral-atom systems can scale far beyond other approaches. The system is a major step toward large-scale quantum simulation and computing.
