Spin-to-charge conversion achieves 95% overall qubit readout fidelity

A team led by Professor Du Jiangfeng and Professor Wang Ya from the Chinese Academy of Sciences (CAS) Key Laboratory of Microscale Magnetic Resonance of the University of Science and Technology of China put forward an innovative spin-to-charge conversion method to achieve high-fidelity readout of qubits, stepping closer towards fault-tolerant quantum computing.
