Many hard problems in quantum computing haven't yet been solved by any one of the big companies involved in that space—companies like Amazon, Google, IBM, or Intel. In the case of a UK-based company called Riverlane, the unsolved piece that is being addressed is the huge amount of data processing that will be needed for a key part of quantum error correction: recognizing when an error has occurred.
