Trapped Ion vs Neutral Atom: Technology Tradeoffs

Trapped Ion (used by IonQ Forte Enterprise 1)
Advantage
Exceptional gate fidelities (99.9%+), long coherence times (seconds to hours), and native all-to-all qubit connectivity eliminate the need for SWAP routing that limits other architectures.
Challenge
Gate operations are slow (microseconds to milliseconds), limiting circuit throughput. Scaling to many ions in a single trap is difficult due to spectral crowding; modular trap architectures are being developed to address this.
Gate Speed
1 µs – 1 ms per gate
Fidelity
99.7–99.99% for 2-qubit gates

Neutral Atom (used by QuEra Aquila)
Advantage
Large qubit counts (100–10,000+ atoms in reconfigurable arrays), programmable connectivity via atom repositioning, and operation at room temperature (atoms laser-cooled to µK). Naturally suited to analog quantum simulation.
Challenge
Gate fidelities are lower than trapped-ion systems, coherence times are shorter, and mid-circuit measurement and classical feedback are still maturing. Rydberg blockade errors limit 2-qubit gate fidelity.
Gate Speed
0.1 µs – 1 ms per gate
Fidelity
98–99.5% for 2-qubit gates
