Scalable On-Hardware Training of Quantum Neural Networks and Application to Clinical Data Imputation

Natansh Mathur, Panagiotis Kl. Barkoutsos, Masako Yamada +2

Training quantum neural networks (QNNs) on quantum hardware is currently bottlenecked by the cost of gradient estimation: standard parameter-shift methods require a number of circu…
