"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 ...

In the world of quantum error correction, an underdog is coming for the king. Last week, new simulations from two groups reported that a rising class of quantum error ...

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 ...

In less than five years, we will have access to an error-free quantum supercomputer – so says IBM. The firm has presented a roadmap for building this machine, called Starling, slated to be available ...
