Make ions count: solving computational problems via quantum simulation
Trapped ions provide flexible emulators of spin Hamiltonians. In this talk, I will motivate to use ions for an implementation of a Mattis-type spin glass model. Finding the ground state of this model is equivalent to the optimization process in the number partitioning problem - a potentially NP-hard computational task. A transverse magnetic field introduces quantum effects, and opens the door to quantum annealing. A numerical study of the system dynamics demonstrates the feasibility of this approach.
