Tight Bounds Reveal Optimal Inference Complexity for Quantum Kernels
Optimal algorithmic complexity of inference in quantum kernel methods for classical data. Quantum kernel methods are among the leading candidates for achieving quantum advantage in supervised machine learning. A key bottleneck is the cost of inference: evaluating a trained model on new data requires estimating a weighted sum. We derive tight upper and lower bounds on the query and gate complexity for different evaluation strategies. https://t.co/1QamxDbesr Warm thanks to @EliesMiquel, Seongwook Shin, @SofieneJerbi, and Maximilian Johannes Kramer for the collaboration.
