"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

I’ll discuss them with respect to RS code but they can be used with all FEC codes, including mixing types of FEC code. Interleaving is simply taking a number of messages and mixing the bytes, in a ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

Last month I showed how coding and error correction allows next-generation broadcast technologies such as DVB-T2 and DVB-NGH to achieve performance very close to the ...

test and verify the Reed-Solomon codec. Each of these steps is important, and missing one results in developing hardware that does not work the first time and must be re-created. For example, it is ...

Communication-system designers have always had to deal with trade-offs among data reliability, efficient use of available spectrum, data throughput, and cost. Error-correction coding (ECC) is one of ...

The controller has to do two sets of writes or reads — one for the data and one for the code, adding latency to each access. Some controllers can pack multiple codes together for sequential data, ...

On grid: oscillator grid states have been used to do quantum error correction in a superconducting qubit. (Courtesy: Shutterstock/Dmitriy-Rybin) A practical ...
