recommendations! Published in 2024 at "npj Quantum Information"

DOI: 10.1038/s41534-025-01036-7

Abstract: Quantum neural networks (QNNs) require an efficient training algorithm to achieve practical quantum advantages. A promising approach is gradient-based optimization, where gradients are estimated by quantum measurements. However, QNNs currently lack general quantum algorithms for… read more here.

DOI: 10.1103/physrevapplied.13.044005

Abstract: The measurement of a quantum system is often performed by encoding its state in a single observable of a light field. The measurement efficiency of this observable can be reduced by loss or excess noise… read more here.

DOI: 10.1371/journal.pone.0300019

Abstract: This paper estimates efficiency measures for the banking system in Chile for the period 2000-2019. In contrast to previous studies, we use input-distance functions, introduce the nonparametric slack-based model, and choose the intermediate inputs approach… read more here.
