Neural-network approach for identifying nonclassicality from click-counting data

Abstract: Machine-learning and neural-network approaches have gained huge attention in the context of quantum science and technology in recent years. One of the most essential tasks for the future development of quantum technologies is the verification of nonclassical resources. Here, we present an artificial neural-network approach for the identification of nonclassical states of light based on recorded measurement statistics. In particular, we implement and train a network which is capable of recognizing nonclassical … Show more

“…These are capable of handling large data sets and of solving tasks for which they have not been explicitly programmed; applications range from stock-price predictions [11,12] to the analysis of medical diseases [13]. In the past few years, several applications of machine-learning methods in the quantum domain have been reported [14][15][16], including state and unitary tomography [17][18][19][20][21][22][23][24][25], the design of quantum experiments [26][27][28][29][30][31][32], the validation of quantum technology [33][34][35], the identification of quantum features [36,37], and the adaptive control of quantum devices [38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54]. Also, photonic platforms can be exploited for the realization of machine-learning protocols [55,56]...…”

“…In recent years, the problem of the classification of unstructured and complex data was increasingly addressed with the help of machine learning techniques [34]. In the quantum domain, a wide range of challenges was tackled using various different forms of machine learning, see, e.g., [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52], and Ref. [53] for a review.…”

“…Recently, there has been an enormous interest in employing artificial neural networks to boost the functionality and robustness of quantum technologies [27][28][29][30][31][32]. In the field of photonics, there has been extensive research devoted to developing artificial neural networks for the implementation of novel optical instruments [33][34][35]. Indeed, convolutional neural networks (CNNs) have enabled the demonstration of new imaging schemes working at the single-photon level [17,36,37].…”
