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 experimentally a robust quantum memory using a magnetic-field-
independent hyperfine transition in Be+ 9 atomic ion qubits at a magnetic field B≃ 0.01194 …

There are several known schemes for entangling trapped ion quantum bits for large-scale
quantum computation. Most are based on an interaction between the ions and external …

We report the implementation of Grover's quantum search algorithm in the scalable system
of trapped atomic ion quantum bits. Any one of four possible states of a two-qubit memory is …

Crystals of trapped atomic ions are among the most promising platforms for the quantum
simulation of many-body quantum physics. Here, we describe recent developments in the …

We demonstrate a simple pulse shaping technique designed to improve the fidelity of spin-
dependent force operations commonly used to implement entangling gates in trapped ion …

Favored schemes for trapped-ion quantum logic gates use bichromatic laser fields to couple
internal qubit states with external motion through a “spin-dependent force.” We introduce a …

One of the first books to thoroughly examine the subject, Quantum Computing Devices:
Principles, Designs, and Analysis covers the essential components in the design of a" real" …

We report on ground-state laser cooling of single Cd+ 111 ions confined in radio-frequency
(Paul) traps. Heating rates of trapped ion motion are measured for two different trapping …

A Mølmer-Sørensen entangling gate is realized for pairs of trapped Cd+ 111 ions using
magnetic-field insensitive “clock” states and an implementation offering reduced sensitivity …
