Here we show that multiqubit tunneling plays a computational role in a currently available, albeit noisy, programmable quantum annealer. We develop a non-perturbative theory of open quantum dynamics under realistic noise characteristics predicting the rate of many-body dissipative quantum tunneling. We devise a computational primitive with 16 qubits where quantum evolutions enable tunneling to the g","authors_text":"Alireza Shabani, Anatoly Smirnov, Hartmut Neven, Mark Dykman, Masoud Mohseni, Mohammad Amin, Sergei V.
