Quantum kernel methods show no significant advantage over tuned classical kernels in new study
A new study published on arXiv evaluates quantum kernel methods for classification tasks, comparing them against classical kernels. The research highlights that hyperparameter tuning of classical kernels, specifically t…

Quantum neural networks overcome amplitude encoding limitations
Researchers have identified a representational limitation in amplitude encoding for quantum neural networks (QNNs), where inputs differing by a nonzero real scaling cannot be distinguished. This invariance, stemming fro…
