Error correction occurs in decoding because there are only limited legal states available at any node on the graph. When the bit stream contains an illegal code, the decoder knows an error occurred.

Error detecting and correcting codes are based on significant distance between two bit strings in terms of the number of bits that have to alter to get from the first ...

Correction is not possible with one parity bit since any bit error in any position creates exactly the same information as bad parity. If more bits are integrated ...

A bosonic qubit developed by Nord Quantique. Made of aluminum, these cavities now contain two tiny "poles", each operating at a different frequency. These additional ...

Eliminating errors in next-generation DNA sequencing has proved challenging. Here we present error-correction code (ECC) sequencing, a method to greatly improve sequencing accuracy by combining ...
