Experimentally Extending Quantum Kernel Learning to Quantum Data by NMR
Researchers demonstrated quantum kernel learning applied directly to quantum data on a nuclear magnetic resonance (NMR) quantum processor. The work extends quantum kernel methods beyond classical data inputs, using NMR to prepare and classify quantum states. The experiment is reported in an arXiv preprint.

This could make NMR testbeds a practical platform for benchmarking quantum-data kernel classifiers on few-qubit systems within two years.
NMR hardware provides high-fidelity small-scale control and is widely available in university labs; if the demonstrated method transfers to common molecules and state preparation protocols, it could serve as a low-cost testbed for comparing quantum kernel approaches before porting them to larger superconducting or trapped-ion machines.
