That said, quantum error correction (QEC) is a complex engineering and physics problem, and a truly satisfactory answer for it appears to be many years away. Today, almost every corporate and academic quantum computing program has some form of error correction research in progress. In 2015, IBM developed the first system to detect quantum bit flip and phase flip errors. IBM has a long history of error correction research, going back as far as investigations in 1996 by David DiVincenzo, Charlie Bennett and John Smolin. The chain is simple-noise causes errors, and uncorrected errors limit the number of qubits you can incorporate in your circuit, which in turn limits algorithm complexity. There is a direct relationship between quantum computing noise and the size of a problem you can tackle.
