In recent years, quantum computers have begun to handle double-digit quantum bits, or qubits. However, many essential applications targeted by quantum computers, such as quantum chemistry, ...

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate. Subscribe to our newsletter ...

"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 ...
