Will quantum computing achieve practical commercial advantage before 2029?

Quantum computing has made significant hardware progress with IBM, Google, and others scaling up qubit counts and reducing error rates. However, the gap between quantum supremacy on contrived benchmarks and practical commercial advantage remains substantial. Error correction, decoherence, and the need for millions of physical qubits for useful computation suggest commercial quantum advantage is still several years away for most applications.

Resolves YES if a peer-reviewed paper or credible industry demonstration shows a quantum computer solving a commercially valuable problem (drug discovery, financial modeling, materials science, logistics optimization) faster or more efficiently than the best available classical computing solution before January 1, 2029. Random circuit sampling or other academic benchmarks do not count.
