Quantum Error Correction in 2025: Progress and Persistent Challenges

Quantum computers hold immense potential, but their greatest weakness is their susceptibility to errors. Unlike classical bits, quantum bits (qubits) are fragile, easily disturbed by environmental noise, imperfect control pulses, and even the act of measurement itself. To build a practical, large-scale quantum computer, robust error correction is essential—yet in 2025, implementing these methods remains …
