# Output: Quantum Error Correction Introduction (English)
Quantum error correction (QEC) represents a fundamental prerequisite for building fault-tolerant quantum computers capable of solving problems beyond classical computational reach (Terhal, 2015). Among various QEC codes, the surface code has emerged as the leading candidate due to its high error threshold (~1%) and compatibility with local qubit interactions on planar architectures (Fowler et al., 2012). Recent experimental demonstrations have achieved logical error rates as low as 10^-6 using distance-7 surface codes on superconducting qubit processors (Google Quantum AI, 2023), marking a significant milestone toward practical quantum computation. However, the overhead in physical qubit count remains substantial, with current implementations requiring approximately 1,000 physical qubits per logical qubit. This review examines recent advances in surface code implementations, discusses the tradeoffs between code distance and resource overhead, and evaluates promising directions for reducing the qubit cost of fault-tolerant quantum computation.
