Quantum Error Correction (QEC) is a critical strategy in quantum computing that protects quantum information from decoherence and noise. It employs codes like Shor, Steane, and Surface codes to correct errors without direct measurement, using superposition and entanglement. QEC's role is vital in advancing secure quantum communication and computing, with ongoing research aimed at developing fault-tolerant systems.
