Experimental demonstration of quantum sensing with a central spin ensemble in hBN, mapping hyperfine interactions, achieving 80 μs coherence under dynamical decoupling and sub-microtesla AC magnetic sensitivity at 10 nm distance.
SAGE qubits gain magnetic protection from singlet-only encoding and always-on exchange but need refocusing pulses and ramp control to maintain coherence and gate performance against charge noise.
