A common type of error-correcting mechanism in biology is called kinetic proofreading. For example, if errors turn up when cells are making new DNA, enzymes can cut out incorrect nucleotides. They can ...

As memory bit cells of any type become smaller, bit error rates increase due to lower margins and process variation. This can be dealt with using error correction to ...

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 ...

Some observers have hailed the response to Covid-19 as a triumph for science. A hesitant triumph, perhaps. Full of missteps and recriminations, frustrations and death. Maybe more a hard-won victory.

In September, Microsoft made an unusual combination of announcements. It demonstrated progress with quantum error correction, something that will be needed for the ...

Quantum bits are fussy and fragile. Useful quantum computers will need to use an error-correction technique like the one that was recently demonstrated on a real machine. In 1994, Peter Shor, a ...
