Technologie / Matériel / Neutral atoms
Neutral atoms
Laser-trapped neutral atoms arranged in programmable arrays.
Le compromis
Points forts: Large arrays; Flexible geometry; Promising scaling.
Défis: Gate fidelity; Atom loss; Control and readout.
Maturité: prototype → early-commercial.
Les vitesses de portes, les fidélités et le nombre de qubits spécifiques ne sont pas publiés ici, ils changent chaque trimestre. Vérifiez auprès des dernières publications techniques de chaque entreprise, pas des communiqués de presse.
