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 ...

"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 ...

The real world can be complex and unpredictable, where the behaviors of even the most steady and proven mechanisms can be fraught with unanticipated outcomes. In technological fields, scientists and ...
