Composition

• gate: 1
• infrastructure: 1
• qubit: 1

Conceptual anchors

• motional-mode-coupling-in-ion-traps is the key evergreen note tying the modality to its entangling-gate layer.
• coherence-time-hierarchy is the right lens for comparing long hyperfine memory times to much faster gate and readout cycles.

Curated synthesis

The most useful way to read this family is as a three-layer stack rather than three unrelated notes.

1. trapped-ion-qubit is the modality baseline

   • Start there when the question is why ions are still canonical: identical qubits, minute-scale coherence, high-fidelity readout, and shared-mode connectivity.
   • It owns the broad platform tradeoff against superconducting and neutral-atom systems.

2. cirac-zoller-gate is the historical mechanism note

   • It explains the original phonon-bus idea in its most literal form: map spin information into motion, apply a conditional phase, map back.
   • Read it when the important question is where trapped-ion entangling gates came from conceptually, not which pulse family dominates today.

3. shuttling-ion-trap-qubit is the scaling architecture note

   • It exists because the same shared-motion resource that gives all-to-all connectivity also stops scaling cleanly in very long chains.
   • QCCD is therefore best understood as an architectural response to motional-mode crowding, not as a new qubit modality.

Routing rule: when to stay here versus hand off

• Stay in this MOC when the question is about the platform-wide logic of trapped ions: why motion is the bus, why long chains saturate, and why transport solves a scaling bottleneck.
• Hand off to ion-trap-moc when the question becomes the modern operational stack built around species-specific clock-state qubits and Mølmer-Sørensen style entangling gates.
• Hand off to neutral-atom-moc when the comparison shifts from Coulomb-crystal buses to tweezer-rearranged atomic arrays with transient Rydberg interactions.

Editorial note

This family should remain the broad modality page. Keep species-specific and gate-stack specialization lightweight here, then route to ion-trap-moc once the reader is really comparing the practical Yb + MS trapped-ion stack.
