Realization of holonomic single-qubit operations

Abstract: Universal single-qubit operations based on purely geometric phase factors in adiabatic processes are demonstrated by utilizing a four-level system in a trapped single $^{40}$Ca$^+$ ion connected by three oscillating fields. Robustness against parameter variations is studied. The scheme demonstrated here can be employed as a building block for large-scale holonomic quantum computations, which may be useful for large qubit systems with statistical variations in system parameters

“…A recent experiment has demonstrated GQC using adiabatic evolution in a tripod configuration, where three ground‐state levels couple to an excited stated by use of three resonant laser fields. This experiment realized a universal set of one‐qubit gates based on the adiabatic scheme proposed in [70] resulting from adiabatic transport of this dark energy eigensubspace for a single trapped ion.…”

“…Theoretical and experimental progress in non-Abelian HQC for single-qubit operations has been made recently, through both adiabatic [60] and nonadiabatic evolution [61][62][63][64] on various of physical systems. Applying our scheme to an actual physical system needs local four-body interactions.…”
