NIST has developed a practical method for automatically correcting data-handling errors in quantum computers using beryllium ions as qubits. The method, demonstrated in NIST’s Boulder laboratories, involves creating redundant data sets (quantum backup copies) and using entangled helper qubits to detect and correct errors without directly measuring the primary qubit. Unlike previous demonstrations, the NIST approach allows qubits to be reset on the fly and could be scaled up for practical quantum computers. The method could be incorporated into quantum computer programs to maintain the fragile quantum states of ions or atoms during data processing.
