Willow Breakthrough
Google's 105-qubit Willow chip (Dec 2024) achieved error rates that decrease exponentially as qubits scale — the first experimental proof of below-threshold error correction. The NISQ era is transitioning to the error-corrected era.
Modular Architecture
IBM Quantum System Two links 3 Heron r2 processors for a 468-qubit platform with cross-processor entanglement, and the 120-qubit Nighthawk (Nov 2025) adds 20% greater connectivity. IBM's roadmap targets Kookaburra (1,386Q) and multi-chip Blue Jay systems later in 2026 — scaling by interconnection rather than chip size.
PQC Migration Market
NIST's 2024 PQC standard finalization (CRYSTALS-Kyber, Dilithium, SPHINCS+) triggers a $15–25B enterprise migration across financial services, government, and critical infrastructure — the largest near-term quantum market driver, requiring no fault-tolerant hardware.
Key Inflection · 2024–2026
Google Willow and IBM Quantum System Two represent the simultaneous crossing of two critical thresholds: below-threshold error correction and modular multi-processor entanglement. North America commands 52% of global quantum revenue; Asia Pacific is the fastest-growing region at 44% CAGR through 2031. The consensus window for first commercial quantum advantage in chemistry and drug discovery: 2029–2031.
