Hyperfine and Optical Barium Ion Qubits

Quantum Physics 2015-05-18 v1

Abstract

State preparation, qubit rotation, and high fidelity readout are demonstrated for two separate \baseven qubit types. First, an optical qubit on the narrow 6S1/2_{1/2} to 5D5/2_{5/2} transition at 1.76 μ\mum is implemented. Then, leveraging the techniques developed there for readout, a ground state hyperfine qubit using the magnetically insensitive transition at 8 GHz is accomplished.
