Tecnologia / Hardware / Trapped ions
Trapped ions
Electromagnetically trapped charged atoms controlled with lasers.
Il tradeoff
Punti di forza: High-fidelity operations; Long coherence; Strong connectivity.
Sfide: Slower gates; Optical complexity; Scaling ion control.
Maturità: early-commercial (cloud access); scaling architectures in progress.
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.
