Alkaline metals electronic transition

Single atomic ions confined in radio frequency traps and cooled by laser beams (Figure 7.4a) formed the basis for the first proposal of a CNOT quantum gate with an explicit physical system [14]. The first experimental realization of a CNOT quantum gate was in fact demonstrated on a system inspired by this scheme [37]. In this proposal, two internal electronic states of alkaline-earth or transition metal ions (e.g. Ba2+ or Yb3+) define the qubit basis. These states have excellent coherence properties, with T2 and T2 in the range of seconds [15]. Each qubit can be... 

Unlike the other alkaline earth and transition metal ions, essentially on account of its small ionic radius and consequent high electron density, Mg2+ tends to bind the smaller water molecules rather than bulkier ligands in the inner coordination sphere. Many Mg2+-binding sites in proteins have only 3, 4 or even less direct binding contacts to the protein, leaving several sites in the inner coordination sphere occupied by water, or in the phosphoryl transferases, by nucleoside di- or triphosphates. 

The transition metals are our premier metals for jewelry making. They have electron configurations that are different from the alkali metals and the alkaline earth metals. Therefore, transition metals exhibit different chemical and physical properties. It is necessary to determine just where electrons reside in transition-metal atoms so we can understand the properties of transition metals and how they bond. To understand these properties and manners of bonding, we must revisit the electron cloud atomic model. 

Complexation studies of sensors 83 and 84 with the alkali, alkaline earth, and transition metal ions Cu2+, Ni2+, Zn2+, Cd2+, and Pb2+ were performed in Valeur s laboratory.141,142 In these compounds, the chromophores are linked to the azacrowns in such a way that the cations interact directly with the carbonyl group that acts as an electron-withdrawing unit. Therefore, when an ion is coordinated,...
