Characterization of charge-exchange collisions between ultracold atoms and ions
R. Saito, S. Haze, M. Sasakawa +5
We investigate the energy dependence and the internal-state dependence of the charge-exchange collision cross sections in a mixture of Li atoms and Ca ions in the co…
Realization of holonomic single-qubit operations
K. Toyoda, K. Uchida, A. Noguchi +2
Universal single-qubit operations based on purely geometric phase factors in adiabatic processes are demonstrated by utilizing a four-level system in a trapped single Ca…
Generation of Dicke states using adiabatic passage
K. Toyoda, T. Watanabe, T. Kimura +3
Entangled states of two ions are realized by using an adiabatic process. Based on the proposal by Linington and Vitanov, we have generated Dicke states in optical qubits of two $^{…
Quantum gate using qubit states separated by terahertz
K. Toyoda, S. Haze, R. Yamazaki +1
A two-qubit quantum gate is realized using electronic excited states in a single ion with an energy separation on the order of a terahertz times the Planck constant as a qubit. Two…
