Machine learning classification of non-Markovian noise disturbing quantum dynamics
This work addresses the problem of classifying noise in quantum systems, which is crucial for benchmarking and improving noisy intermediate-scale quantum devices.
This paper proposes machine learning models, specifically support vector machines, multi-layer perceptrons, and recurrent neural networks, to classify external non-Markovian noise sources disturbing quantum dynamics. The models achieved high efficacy in classifying noisy quantum dynamics using simulated data, demonstrating that only discrete-time measurements of quantum system probabilities are needed for successful classification.
In this paper machine learning and artificial neural network models are proposed for the classification of external noise sources affecting a given quantum dynamics. For this purpose, we train and then validate support vector machine, multi-layer perceptron and recurrent neural network models with different complexity and accuracy, to solve supervised binary classification problems. As a result, we demonstrate the high efficacy of such tools in classifying noisy quantum dynamics using simulated data sets from different realizations of the quantum system dynamics. In addition, we show that for a successful classification one just needs to measure, in a sequence of discrete time instants, the probabilities that the analysed quantum system is in one of the allowed positions or energy configurations. Albeit the training of machine learning models is here performed on synthetic data, our approach is expected to find application in experimental schemes, as e.g. for the noise benchmarking of noisy intermediate-scale quantum devices.
