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

But even then, errors can creep in, and occur at much greater rates than in classical devices. Logical operations in Google’s state-of-the-art quantum processor fail at a rate of about 1 in 100, says ...

Today's quantum processors are error-prone. While the probabilities are small—less than 1 percent in many cases—each operation we perform on each qubit, including ...
