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 کاملStrontium ions as a probe for the role of alkaline-earth metal ions in histamine secretion [proceedings].
granule-membrane surface as it undergoes exocytosis is dramatically decreased (Howell & Tyhurst, 1977). Incubation of isolated granules with 1-2m~-CaCI, did not produce a visible decrease in the number of anionic sites, although as shown by Dean (1974), even the small decrease in charge which could be expected after addition of 1 mM-CaZ+ would be sufficient to produce a 50-fold increase in the ...
متن کاملInteraction of Alkaline Earth Metal Ions with Acetic and Lactic Acid in Aqueous Solutions
Interaction of alkaline earth metal (magnesium, calcium, strontium and barium) ions with acetic and lactic acid in aqueous media was investigated by C NMR spectroscopy. In the acetate systems, signals whose chemical shifts were the averages of those of the free and bound acetate ions were observed. Downfield shifts of the carboxylate carbon signals with increasing metal ion concentration indica...
متن کاملDansyl - Substituted Aza Crown Ethers: Complexation with Alkali, Alkaline Earth Metal Ions and Ammonium.
The present study investigates the binding properties of four dansyl substituted aza-crown ethers with alkali, alkaline earth metal ions and ammonium. The influence of the solvent polarity and protonation on the photophysical properties of the compounds was studied by UV/Vis and fluorescence methods. The host species caused only slight changes on the absorption spectra of the ligands. The fluor...
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...
