If a small quantum laptop makes a small variety of errors, will a big quantum laptop make much more errors, making it fully ineffective? No, say researchers at Google who’ve made a key breakthrough in error correction for quantum units, setting out a theoretical path to creating machines which can be helpful and sensible.
Unusual computer systems retailer information as bits which can be both a 0 or 1, however errors could cause the bit to “flip” to the unsuitable worth, which is why units from smartphones to supercomputers have built-in error correction.…
