Технологии / Железо / Neutral atoms
Neutral atoms
Laser-trapped neutral atoms arranged in programmable arrays.
Компромисс
Преимущества: Large arrays; Flexible geometry; Promising scaling.
Сложности: Gate fidelity; Atom loss; Control and readout.
Зрелость: prototype → early-commercial.
Specific gate speeds, fidelities and qubit counts are not published here, they change quarterly. Verify against each company's latest technical publications, not press releases.
