IonQ (founded 2015) pioneered commercial trapped ion quantum computers with industry-leading gate fidelities. Using individual ytterbium-171 ions suspended in electromagnetic traps, IonQ achieves 99.9%+ single-qubit and 99.5%+ two-qubit gate fidelities—highest among all quantum computing platforms. All-to-all connectivity eliminates SWAP overhead, enabling efficient circuit execution.
💡 Why Trapped Ions?
Identical qubits: All ions naturally identical—no fabrication variation. Long coherence: T2 >1 second—orders of magnitude better than superconducting qubits. All-to-all connectivity: Any ion can interact with any other—no nearest-neighbor constraints.
🎯 What You'll Learn
🏗️ Trapped Ion Advantages
All ytterbium-171 ions are atomically identical—no fabrication variation like superconducting qubits. Every qubit has same energy levels, transition frequencies, and coherence properties.
Hyperfine qubits protected from environmental noise—orders of magnitude longer than superconducting qubits (~100 μs). Enables deep quantum circuits with 100+ gates.
Only ions need cooling, not entire system—control electronics at room temperature. Reduces complexity compared to dilution refrigerators for superconducting qubits.
