Researchers at Yale University have designed a system to prevent future quantum computers from "leaking" errors in ancillary quantum bits (qubits) to logical qubits.

Such leakage introduces more errors than the ancillary qubits are able to correct.

The researchers say they have addressed this problem by enhancing the system's fault tolerance. Yale's Philip Reinhold says this "essentially amounts to making a robust system out of faulty parts," opening the way for error correction that increases quantum computation's fidelity.

Yale's Serge Rosenblum says the method reduces the odds of catastrophic failure during error detection in quantum systems by a factor of five.
