Quantum error‐correcting codes (QECCs) have emerged as a crucial instrument in the quest to realise reliable quantum information processing. These codes utilise sophisticated mathematical frameworks ...

On Tuesday, IBM released its plans for building a system that should push quantum computing into entirely new territory: a system that can both perform useful calculations while catching and fixing ...

Every online bank transfer, private message and Bitcoin transaction rests on the assumption that some math problems are practically impossible to solve. Quantum computers threaten to flip that ...

“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 ...
