Quantum computing with alkaline-Earth-metal atoms.
We present a complete scheme for quantum information processing using the unique features of alkaline-earth-metal atoms. We show how two completely independent lattices can be formed for the 1S0 and 3P0 states, with one used as a storage lattice for qubits encoded on the nuclear spin, and the other as a transport lattice to move qubits and perform gate operations. We discuss how the 3P2 level c...
متن کاملAlkaline-earth-metal atoms as few-qubit quantum registers.
We propose and analyze a novel approach to quantum information processing, in which multiple qubits can be encoded and manipulated using electronic and nuclear degrees of freedom associated with individual alkaline-earth-metal atoms trapped in an optical lattice. Specifically, we describe how the qubits within each register can be individually manipulated and measured with subwavelength optical...
متن کاملSemiempirical calculation of van der Waals coefficients for alkali-metal and alkaline-earth-metal atoms
The van der Waals coefficients, C6 , C8, and C10 for the alkali-metal ~Li, Na, K, and Rb! and alkaline-earthmetal ~Be, Mg, Ca, and Sr! atoms are estimated by a combination of ab initio and semiempirical methods. Polarizabilities and atom-wall coefficients are given as a diagnostic check, and the lowest order nonadiabatic dispersion coefficient, D8 and the three-body coefficient, C9 are also pre...
متن کاملCross Sections for the Collisions of Alkaline Earth Atoms
The total attenuation cross sections, a*, were measured for collisions of an excited atomic beam of Mg, Ca or Sr with a target of Cl2 molecules. The experimental o* values equal: 85 Ä2, 100 Ä2 and 180 Ä2 for Mg*, Ca* and Sr*, respectively. Moreover, the reactive cross sections, OR were calculated, assuming the "harpoon mechanism" for the reactions in question. The obtained values are: OR* (Mg* ...
متن کاملState-dependent lattices for quantum computing with alkaline-earth-metal atoms
Recent experimental progress with Alkaline-Earth atoms has opened the door to quantum computing schemes in which qubits are encoded in long-lived nuclear spin states, and the metastable electronic states of these species are used for manipulation and readout of the qubits. Here we discuss a variant of these schemes, in which gate operations are performed in nuclear-spin-dependent optical lattic...
