Abstract
A single laser–cooled and trapped 9Be+ ion is used to investigate methods of coherent quantum–state synthesis and quantum logic. We create and characterize non–classical states of motion including ‘Schrodinger–cat’ states. A fundamental quantum logic gate is realized which uses two states of the quantized ion motion and two ion internal states as qubits. We explore some of the applications for, and problems in realizing, quantum computation based on multiple trapped ions.
