Trapped Ion vs Photonic: Technology Tradeoffs
- 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
- Advantage
- Operates at room temperature (no cryogenics required), photons travel at the speed of light with minimal decoherence, and photonic hardware is compatible with existing fiber-optic telecommunications infrastructure for quantum networking.
- Challenge
- Deterministic photon-photon interactions are extremely difficult to engineer, making universal fault-tolerant quantum computation challenging. High photon loss rates and detector inefficiencies limit circuit depth. Current GBS machines are specialized rather than general-purpose.
- Gate Speed
- Picoseconds for passive operations; detector timing ~ns
- Fidelity
- Variable; loss-dominated; ~98% for single-photon detectors
Use Case Recommendations
Higher 2Q gate fidelity (99.70%) means fewer errors in VQE/UCCSD circuits.
All-to-all connectivity maps optimization problems directly without SWAP overhead.
Higher CLOPS (200) means faster circuit execution for high-repetition workloads.
