Phys.org  September 1, 2022 The fundamental challenge to quantum computers is that the operations are noisy. Rather than focusing solely on reducing the number of errors a team of researchers in the US (Yale University, University of Wisconsin-Madison, Princeton) made errors more visible. They delved deeply into the actual physical causes of error and engineered their system so that the most common source of error effectively eliminates, rather than simply corrupting, the damaged data leading to “erasure error,” which is fundamentally easier to weed out than data that is corrupted but still looks like all the other data. Erasure errors […]
