Quantinuum

Joint engineering is underway. No volumes, economics, dates, or component assignments disclosed. The IPO prospectus already named Quanta Computer a partner.

Quantinuum's result demonstrates a universal topological gate set on conventional qubits, while the resource advantage that matters remains unproven.

Quantinuum's H2 trapped-ion processor claims quantum magnetism simulation beyond classical tensor network reach. Materials science utility undemonstrated.

Phantom codes, QLDPC codes, iceberg codes, cat qubits, neural decoders. Five years ago, surface codes were the only game in town. Now there's a genuine competition, and it might get us to fault tolerance faster than any single approach could.
