Scientists have achieved the lowest quantum computing error rate ever recorded — an important step in solving the fundamental challenges on the way to practical ...

For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...

However, the process of detecting and correcting any errors is complicated by the fact that you can’t directly measure the states of the physical qubits without causing them to collapse. "So you have ...
