A strategy for quantum algorithm design assisted by machine learning
New Journal of Physics, 2014 We propose a method for quantum algorithm design assisted by machine learning. The method uses a quantum–classical hybrid simulator, where a ‘quantum student’ is being taught by a ‘classical teacher’. In other words, in our method, the learning system is
