Abstract: Coherent Quantum State Manipulation Of Trapped Atomic Ions’

A single, laser-cooled, trapped %e ’ ion is used to investigate methods of coherent quantum-state synthesis. We create and characterize nonclassical states of motion including “Schrodinger-cat ” states. A fbndamental quantum logic gate is realized using the quantized motion and internal states as qubits. We explore some of the applications for, and problems in realizing, quantum computation based on multiple trapped ions
