Experimental realization of a universal set of adiabatic quantum gates with NV center in diamond

To realize quantum computer, a universal set of quantum logic gates is the basic requirement. Besides commonly used dynamical way, the geometric approach is recommended for its advantage of intrinsically noise-resilience feature. Experimental realization of a universal set of geometric quantum gates have already been reported with solid-state spins in nitrogen-vacancy diamond using non-adiabatic holonomies. However, non-adiabatic process is somewhat constrained in parameter value choosing, compared to adiabatic gates. Here, we realize a universal set of geometric quantum logic gates with adiabatic process in NV center system. The adiabatic gates are demonstrated to be robust against experimental control parameters for a wide range. These results suggest that any adiabatic geometric quantum algorithm can be realized in solid-state qubits, alongside its robustness to experimental parameters.
