Many-body quantum networks and adiabatic quantum computing

Adiabatic quantum computing (AQC) is a form of quantum computing at the forefront of quantum technologies. Cutting-edge prototypes of quantum annealing devices have by now been developed (e.g. by D-wave) and explored by Google, NASA and LANL, among other companies and institutions. In essence, AQC exploits the application of the quantum adiabatic theorem to find the ground state of many-body Hamiltonians that encode the solution of a complex optimization problem of interest. Realistic annealing schedules in finite-time often lead to nonadiabatic dynamics and formation of excitations.
