This study experimentally validates quantum kernel learning (QKL) on liquid-state NMR hardware, demonstrating its ability to efficiently process quantum data without expensive tomography protocols. By benchmarking QKL against classical methods for regression and classification tasks, the research confirms that encoding feature maps into Hilbert spaces offers a practical advantage for capturing inherent structures in operator space. The work effectively bridges theoretical machine learning concepts with native quantum implementation using 3-qubit registers to handle both entangling and non-entangling operators.
Experimentally Extending Quantum Kernel Learning to Quantum Data by NMR
arXiv:2412.09557v3 Announce Type: replace-cross Abstract: Quantum kernel learning (QKL) promises efficient machine learning by encoding feature maps onto exponentially large Hilbert spaces inherent in quantum systems. Using the liquid-state nuclear magnetic resonance (NMR) platform, we implement and benchmark QKL for one-dimensional regression and two-dimensional classification tasks. We then classify entangling and non-entangling operators by extending QKL to handle parametrized or non-parameterized operator inputs. We first compute the kernel numerically for a double-layered star system and then experimentally validate it on a 3-qubit NMR register. QKL provides a practical route to compare operators on native quantum hardware without expensive tomography protocols. Our results confirm the superiority of QKL over other classical methods for processing quantum data, thereby highlighting its ability to capture the inherent structure of quantum space and to extend its domain of operation beyond the training domain by exploiting symmetries in the operator space.
