Vendor Roadmaps

Last updated: September 25, 2026

Figures are as published by each vendor. LQ logical qubits · PQ physical qubits.

Quantum hardware roadmap milestones by vendor and year, 2026–2030, as published by each vendor. Counts are logical (LQ) or physical (PQ) qubits.

The industry is transitioning from the NISQ era to the FTQC era, and some vendors publish physical qubits (PQ) and logical qubits (LQ). Rigetti only publishes physical qubits. It would be safe to conclude that milestones with physical qubit counts are NISQ era machines, and milestones with logical qubits are FTQC era machines.

Not all logical qubits are created equal. Different modalities introduce different effects such as speed and coherence time. Different vendors use different error-correcting codes. Some problem types and algorithms will perform well with 800 logical qubits, others won’t.

Roadmaps are useful for assessing the evolution of technology. Sometimes roadmaps are aspirational, sometimes they are firm commitments. My approach: this is what the vendors say and I will hold them to it until new information causes a change.

This data gives us a directional sense on where vendors are with their programs today and where they intend to be in the future. Ultimately, what will matter most is if a computer can solve a problem and what the Cost of Solution and Time to Solution are.

I will update this page as new information becomes available. Feel free to reach out with questions or corrections via the Contact page.
