Reinforcement Quantum Annealing: A Quantum-Assisted Learning Automata Approach

no code implementations1 Jan 2020 Ramin Ayanzadeh, Milton Halem, Tim Finin

We introduce the reinforcement quantum annealing (RQA) scheme in which an intelligent agent interacts with a quantum annealer that plays the stochastic environment role of learning automata and tries to iteratively find better Ising Hamiltonians for the given problem of interest.
