## Quantum Error Correction: Why Fault-Tolerant Computing Is Still a Decade Away Google's Willow chip made headlines in 2024 for solving a specific benchmark problem exponentially faster than classical computers. But that benchmark was designed for quantum hardware — not for the cryptography or drug discovery problems that matter. The real gap: you need ~1 million physical qubits to implement one logical qubit with sufficient error correction. **In the full node:** Surface code overhead, physical vs logical qubit economics, what the Willow results actually mean, and realistic timelines for fault-tolerant quantum advantage. 📖 [Read: Quantum Error Correction](/node/2021)
