Approaching near theoretical maximum limit (hashing bound) for error-correction accuracy for large-scale quantum computing

"quantum computers use wave interference to find answers in single sweep rather than checking 1 by 1, but creates noise, a built-in flaw making some errors inevitable... overcome by preventing ripple effect from working at scale... remains ultra-fast even when dealing with millions of qubits, enabling large-scale machines... applications: (1) drug discovery: simulating complex molecules, (2) cryptography: creating ultra-secure communication, (3) climate science: building more accurate prediction models"
