This is another hype piece from Google's research and development arm. This is a theoretical application to increase the number of logical qubits in a system by decreasing the error caused by quantum circuts. They just didn't do the last part yet so the application is yet to be seen.

"Our results present device performance that, if scaled, could realize the operational requirements of large scale fault-tolerant quantum algorithms."

Google forgot to test if it scales I guess?
