Quantum thesis

Rigetti is a pure-play superconducting quantum computing company that designs its own multi-chip processors and operates a quantum cloud platform. The thesis rests on superconducting qubits being the same architecture used by IBM and Google, with Rigetti positioned as the smallest-cap way to own that approach. Execution risk is high, revenue is research-grade, and the share count has expanded materially.

Quantum thesis

IBM runs the most mature commercial quantum program of any public company. IBM Quantum operates a fleet of superconducting processors over the cloud, publishes a detailed hardware roadmap, and ships Qiskit, the most widely used open-source quantum software stack. Quantum is a tiny share of IBM revenue, but no other diversified bet has more direct quantum exposure or a longer track record.
