Erasure conversion for singlet-triplet spin qubits enables high-performance shuttling-based quantum error correction
The research shows that using singlet-triplet (ST) spin qubits is a superior way to perform shuttling-based quantum error correction compared to other methods. By treating leakage noise as an error type, the ST encoding allows for automatic detection and correction of errors without extra classical control. This leads to significantly higher error thresholds and lower logical error rates, making it a practical path toward fault-tolerant quantum computing.
