Rigetti Computing (RGTI) Cantor Fitzgerald Global Technology Conference summary

Company background and technology overview

• Founded in 2013, the company is a full-stack quantum computing developer with in-house chip design and fabrication, holding about 230 patents.

• Specializes in superconducting gate-based quantum computing, leveraging semiconductor industry expertise for scalability.

• Competes with major tech firms and global players in the superconducting quantum computing space.

Quantum computing modalities and industry trends

• Superconducting gate-based quantum computing offers advantages in scalability and gate speed, now matching or exceeding other modalities in fidelity.

• Recent industry announcements show superconducting approaches achieving 99.5–99.7% fidelity, closing the gap with trapped ion and photonics.

• Investment and R&D are heavily concentrated in superconducting modalities, with major tech and government backing.

Roadmap and scalability plans

• Current systems feature 84 qubits at 99.5% median 2-qubit gate fidelity, with plans to exceed 100 qubits using a chiplet approach by year-end.

• Targeting 1,000+ qubits and 99.9% fidelity within 4–5 years, aiming for real-time error correction and quantum advantage.

• Logical qubits remain low industry-wide; 50–100 logical qubits at 1,000 physical qubits would rival today’s top supercomputers.
