Unlike prior approaches that rely on Classical Fisher Information derived from measurement outcomes, QEWC uses Quantum Fisher Information (QFI) to identify which parameters in a variational quantum circuit are most critical to preserving previously learned tasks. By protecting high-QFI parameters during sequential training, the framework balances stability and plasticity in a geometry-native way. Tested on four-qubit simulated classifiers across MNIST, Fashion-MNIST, and quantum phase classification tasks, QEWC outperformed unregularized training and showed more robustness to simulated depolarizing noise than classical EWC. Limitations include reliance on classical simulation, use of only diagonal QFI approximations, and small benchmark scale — with real hardware validation left for future work. ## Full article daily.dev links to this article rather than hosting it.
