A good native toffoli is a useful bootstrap for magic state distillation, which is relevant to long term error correction costs.
...but since they haven't actually experimentally validated the gate, it's a bit early to say it would actually help. The control error in coupling 3+ qubits simultaneously might just wipe out any benefit over decomposing into smaller gates. That being said I'm not an experimentalist so my knowledge of control error scaling in an ion trap is roughly 0.
- reikonomusha 5y agoThat's very true. It's be nice they'd suggest such potential niche uses instead of emblazoning "arithmetic!" or "VQE!" on the press release.
