Quantum State Engineering using Single Nuclear Spin Qubit of Optically Manipulated Ytterbium Atom

Abstract

A single Yb atom is loaded into a high-finesse optical cavity with a moving lattice, and its nuclear spin state is manipulated using a nuclear magnetic resonance technique. A highly reliable quantum state control with fidelity and purity greater than 0.98 and 0.96, respectively, is confirmed by the full quantum state tomography; a projective measurement with high speed (500us) and high efficiency (0.98) is accomplished using the cavity QED technique. Because a hyperfine coupling is induced only when the projective measurement is operational, the long coherence times (T_1 = 0.49 s and T_2 = 0.10 s) are maintained. Our technique can be applied for implementing a scalable one-way quantum computation with a cluster state in an optical lattice.
