Huge quantum computing progress and acceleration Chinese scientists just developed a powerful new technique that uses precise microwave pulses to fix one of quantum computing’s most stubborn problems that's qubit leakage, where quantum information escapes into unusable energy states and corrupts calculations. Instead of adding complex hardware, researchers apply carefully timed microwave signals that actively push leaked qubits back into their correct computational states while the system is running. The method was demonstrated on a large superconducting processor built by USTC China. In experiments, this approach suppressed leakage errors by more than 70× and, critically, made larger quantum systems more reliable instead of less, a key requirement for fault-tolerant quantum computing.
