High-fidelity quantum logic gates using trapped-ion hyperfine qubits
C. J. Ballance, T. P. Harty, N. M. Linke +2
We demonstrate laser-driven two-qubit and single-qubit logic gates with fidelities 99.9(1)% and 99.9934(3)% respectively, significantly above the approximately 99% minimum threshol…
Dark-resonance Doppler cooling and high fluorescence in trapped Ca-43 ions at intermediate magnetic field
D. T. C. Allcock, T. P. Harty, M. A. Sepiol +5
We demonstrate simple and robust methods for Doppler cooling and obtaining high fluorescence from trapped 43Ca+ ions at a magnetic field of 146 Gauss. This field gives access to a…
Hybrid quantum logic and a test of Bell's inequality using two different atomic isotopes
C. J. Ballance, V. M. Schaefer, J. P. Home +9
Entanglement is one of the most fundamental properties of quantum mechanics, and is the key resource for quantum information processing. Bipartite entangled states of identical par…
