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-corrected magic: Clifford circuits attain universality – that is, the ability to compute any function that quantum theory permits – upon injection of special states called magic states.

Researchers from Google have demonstrated a new generation of quantum computer, called Willow, which is able to run its random circuit sampling (RCS) benchmark significantly faster than a ...

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.

Cambridge, UK – 4th September 2025 — Quantum error correction company Riverlane today announced that it will deploy its QEC technology, Deltaflow 2, at the ...

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 ...
