"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 ...

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 ...
