Paper on control of beryllium ions with an UV frequency comb published in PRL

In our latest paper we demonstrated quantum control of 9Be+ ions directly implemented by an optical frequency comb.

Based on numerical simulations of the relevant processes in 9Be+ for different magnetic field regimes, we demonstrated a wide applicability when controlling the comb’s spectral properties. We introduced a novel technique for the selective and efficient generation of a spectrally tailored narrow-bandwidth optical frequency comb near 313 nm. We experimentally demonstrated internal state control and internal-motional state coupling of 9Be+ 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.
