This is achieved after training the network with a collection of known inputs and results leading to an adjustment of the neuron connections and biases. In the context of quantum detection schemes, neural networks find a natural playground. In particular, in the presence of a target, a quantum sensor delivers a response, i.e., the input data, which can be subsequently processed by a neural network that outputs the target features. We demonstrate that adequately trained neural networks enable to characterize a target with minimal knowledge of the underlying physical model, in regimes where the quantum sensor presents complex responses, and under a significant shot noise due to a reduced number of measurements. We exemplify the method with a development for $^{171}$Yb$^{+}$ atomic sensors. However, our protocol is general, thus applicable to arbitrary quantum detection scenarios.", "revisions": [ { "version": "v2", "updated": "2021-08-12T07:52:41.000Z" } ], "analyses": { "keywords": [ "quantum detection", "neural-network-based parameter estimation", "trained neural networks enable", "neural networks bridge input data", "artificial neural networks bridge input" ], "tags": [ "journal article" ], "publication": { "publisher": "IOP" }, "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable" } } }
