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 ...

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

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.

In this paper, we investigate an architectural-level mitigation technique based on the coordinated action of multiple checksum codes, to detect and correct errors at run-time.

Whenever we send data — whether it’s audio signals over a phone line, a data stream or a legal document — to someone else, we need to know that what arrives on the other end is identical to what we ...
