Deep Learning for Quantum Sensing

Scheme of the implemented deep learning protocol.
Scheme of the implemented deep learning protocol. A limited number of quantum probe states are fed into the sensor treated as a black box. A grid of measurement results is collected to train a neural network, which learns the posterior probability distribution associated with the single-measurement Bayesian update. Such distribution is used to define the reward of the RL agent that sets the control phases on the black-box device. Image credit: Cimini et al., doi 10.1117/1.AP.5.1.016005

Quantum sensing represents one of the most promising applications of quantum technologies, with the aim of using quantum resources to improve measurement sensitivity...
