Quantum Error Correction: The Key Barrier to Large-Scale Quantum Computing
As the race toward practical quantum computing intensifies, researchers and industry leaders alike are confronting a formidable obstacle: quantum error correction (QEC). While quantum computers promise exponential speedups for certain problems—such as cryptography, optimization, chemistry simulations, and advanced machine learning tasks—scaling them from a few qubits to millions remains a monumental challenge. At the heart…
