Quantum information processing using optical transitions in ions has been successful for many experiments. Alternatively, quantum information can also be encoded in ground states and processed by lasers driving Raman transitions. This leads to longer coherence times as laser frequency fluctuations have no effect. Here, we report on single qubit operations on ground state qubits in 40Ca+. We characterize the performance of single qubit operations using randomized benchmarking. In order to produce the required number of gates, a new FPGA based control system had to be implemented to allow for longer sequences.
