Roadmap Target
Proteus commercial launch late 2026 (18+ amino acids, ~1,000× throughput); 20 of 20 amino acids by 2027
Quantum-Si is NOT a quantum computing company. It uses quantum tunneling detection in a CMOS semiconductor chip for single-molecule protein sequencing (proteomics). Current product: Platinum Pro (launched Jan 2025, V4 kit detects 17 of 20 amino acids). Next-gen: Proteus instrument (late 2026 commercial launch target) — 18+ amino acids at launch, tens of millions of peptides per experiment (vs. tens of thousands on Platinum Pro), ~90 min run time. Successful sequencing on integrated Proteus instruments (April 2026, KinetIQ Array dev kit, 17 amino acids); Early Access Program summer 2026.
