Coherent oscillations in diabatic quantum annealing schedules

ORAL

Abstract

Diabatic transitions in quantum annealing protocols provide a potential route to speedup over classical algorithms via bypassing adiabatic ground state evolution. Theoretical studies involving multiple diabatic transitions show oscillations in the ground state probability as a function of anneal time, highlighting the importance of coherence in quantum annealing. We discuss the path towards the experimental study of this effect, using single and multiple qubits and present some recent experimental results on capacitively-shunted flux qubits which provide insight into the role of coherence and noise in small-gap settings.
