Quantum computation and communication exploit the quantum properties of superposition
and entanglement in order to perform tasks that may be impossible using classical means. In …

Quantum teleportation is the faithful transfer of quantum states between systems, relying on
the prior establishment of entanglement and using only classical communication during the …

We demonstrate the use of trapped ytterbium ions as quantum bits for quantum information
processing. We implement fast, efficient state preparation and state detection of the first …

Trapped atomic ions are among the most attractive implementations of quantum bits for
applications in quantum-information processing, owing to their long trapping lifetimes and …

We analyze the error in trapped-ion, hyperfine qubit, quantum gates due to spontaneous
scattering of photons from the gate laser beams. We investigate single-qubit rotations that …

This second volume of the Charged Particle Traps deals with the rapidly expanding body of
research exploiting the electromagnetic confinement of ions, whose principles and …

We report the first detection of elements at all three r-process peaks in the metal-poor halo
star HD 160617. These elements include arsenic and selenium, which have not been …

Simultaneous measurement of multiple qubits stored in hyperfine levels of trapped 111Cd+
ions is realized with an intensified charge-coupled device (CCD) imager. A general theory of …

Abstract The Multi Ion Reflection Apparatus for Collinear Laser Spectroscopy (MIRACLS)
seeks to extend the reach of high-resolution collinear laser spectroscopy (CLS) to more …

We present a precise measurement of the lifetime of the 6 p P 2 1/2 o excited state of a
single trapped ytterbium ion (Yb+). A time-correlated single-photon counting technique is …
