Trapped ions are among the most promising systems for practical quantum computing (QC).
The basic requirements for universal QC have all been demonstrated with ions, and …

Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes
of the controlling parameters of a system. The shortcuts are designed by a set of analytical …

We report high-fidelity laser-beam-induced quantum logic gates on magnetic-field-
insensitive qubits comprised of hyperfine states in Be 9+ ions with a memory coherence time …

Trapped atomic ions are standards for quantum information processing, serving as quantum
memories, hosts of quantum gates in quantum computers and simulators, and nodes of …

Quantum computers have made extraordinary progress over the past decade, and
significant milestones have been achieved along the path of pursuing universal fault-tolerant …

We demonstrate remote entanglement of trapped-ion qubits via a quantum-optical fiber link
with fidelity and rate approaching those of local operations. Two Sr+ 88 qubits are entangled …

The trapped-ion quantum charge-coupled device (QCCD) proposal, lays out a blueprint for a
universal quantum computer that uses mobile ions as qubits. Analogous to a charge …

Quantum adiabatic processes—that keep constant the populations in the instantaneous
eigenbasis of a time-dependent Hamiltonian—are very useful to prepare and manipulate …

We discuss mini MS systems in terms of individual components and at a systems level.
Portable systems from academic and commercial laboratories are emphasized, but meso …

Electric-field noise near surfaces is a common problem in diverse areas of physics and a
limiting factor for many precision measurements. There are multiple mechanisms by which …
