Qubits encoded in hyperfine states of trapped ions are ideal for quantum computation given their long lifetimes and low sensitivity to magnetic fields, yet they suffer from off-resonant scattering during detection often limiting their measurement fidelity. In Yb this is exacerbated by a low fluorescence yield, which leads to a need for complex and expensive hardware – a problematic bottleneck especially when scaling up the number of qubits. We demonstrate a detection routine based on electron…
