California Institute of Technology researchers build largest quantum computer array with 6,100 qubits

California Institute of Technology researchers have successfully built the largest quantum computer array to date with 6,100 qubits. This breakthrough in neutral atom technology offers a promising path toward fault-tolerant quantum computing. The new array maintains qubit coherence for approximately 13 seconds and achieves individual qubit manipulation with 99.98% accuracy. This significant advancement addresses the challenge of scaling up qubit numbers without sacrificing quality, a crucial step for practical quantum computers. Achieving fault tolerance is estimated to require millions of qubits. This development, utilizing laser-trapped neutral atoms, represents a major milestone in the quest for large-scale, high-quality quantum computing systems.
