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 …

Atomic ions trapped in electromagnetic potentials have long been used for fundamental
studies in quantum physics. Over the past two decades, trapped ions have been …

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 …

By isolating from the environment and precisely controlling mesoscopic objects, levitation in
vacuum has evolved into a versatile technique that has already benefited diverse scientific …

We demonstrate tunable spin-spin couplings between trapped atomic ions, mediated by
laser forces on multiple transverse collective modes of motion. A σ x σ x-type Ising …

We investigate a surface-mounted electrode geometry for miniature linear radio frequency
Paul ion traps. The electrodes reside in a single plane on a substrate, and the …

The electromagnetic manipulation of isolated atoms has led to many advances in physics,
from laser cooling and Bose–Einstein condensation of cold gases to the precise quantum …

Quantum Information Processing is a young and rapidly growing field of research at the
intersection of physics, mathematics, and computer science. Its ultimate goal is to harness …

Multipole radiofrequency ion traps are a highly versatile tool to study molecular ions and
their interactions in a well-controllable environment. In particular the cryogenic 22-pole ion …

Ions confined using a Paul trap require a stable, high voltage and low noise radio frequency
(RF) potential. We present a guide for the design and construction of a helical coil resonator …
