There are different methods of removing 鈥noise鈥 from quantum data. One such method is called 鈥減ost processing鈥, where results from a quantum calculation are compared against data from classical computers so that 鈥渘oise鈥 can be identified and removed after a computation is completed. This is a useful technique during this early stage of quantum computing to verify and validate calculations. But this will not be feasible as quantum computers scale and we begin tackling calculations too complex for classical computers.
