Why the Surface Code Wins for Now: How Hardware Connectivity Shapes Quantum Error Correction
The surface code has become the practical choice for near-term quantum computers because its local connectivity requirements align with current hardware capabilities, particularly superconducting circuits. This hardware-driven decision framework highlights the trade-off between a code's error-correcting power and its demands on physical qubit interactions.

The Quantum Scaling Problem: Why Error Correction Demands Massive Resources
Building large-scale quantum computers faces a major obstacle: the inherent fragility of qubits and high error rates from decoherence and crosstalk. Quantum error correction offers a path to fault-tolerance but demands a massive overhead, requiring thousands of physical qubits for a single stable logical qubit.
