Versatile control of ${}^9$Be${}^{+}$ ions using a spectrally tailored UV frequency comb

Abstract

We demonstrate quantum control of ${}^9$Be${}^{+}$ ions directly implemented by an optical frequency comb. Based on numerical simulations of the relevant processes in ${}^9$Be${}^{+}$ for different magnetic field regimes, we demonstrate a wide applicability when controlling the comb's spectral properties. We introduce a novel technique for the selective and efficient generation of a spectrally tailored narrow-bandwidth optical frequency comb near 313 nm. We experimentally demonstrate internal state control and internal-motional state coupling of ${}^9$Be${}^{+}$ ions implemented by stimulated-Raman manipulation using a spectrally optimized optical frequency comb. Our pulsed laser approach is a key enabling step for the implementation of quantum logic and quantum information experiments in Penning traps.
