Long-lived qubit memory using atomic ions

C. Langer, R. Ozeri, J. D. Jost +13

We demonstrate experimentally a robust quantum memory using a magnetic-field-independent hyperfine transition in 9Be+ atomic ion qubits at a magnetic field B ~= 0.01194 T. We obser…

Sympathetic cooling of $^{9} B e^{+}$ and $^{24} M g^{+}$ for quantum logic

M. D. Barrett, B. DeMarco, T. Schaetz +9

We demonstrate the cooling of a two species ion crystal consisting of one $^{9} B e^{+}$ and one $^{24} M g^{+}$ ion. Since the respective cooling transitions of these two species are separa…
