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 …

Trapped-ion quantum information processors store information in atomic ions maintained in
position in free space by electric fields. Quantum logic is enacted through manipulation of …

We report on the first demonstration of transport of a multispecies ion crystal through a
junction in a rf Paul trap. The trap is a two-dimensional surface-electrode trap with an X …

Motional heating of trapped atomic ions is a major obstacle to their use as quantum bits in a
scalable quantum computer. The detailed physical origin of this heating is not well …

In this paper, we report the design, fabrication and preliminary testing of a 150 zone ion trap
array built in a 'surface-electrode'geometry microfabricated on a single substrate. We …

Numerical simulation of quantum systems is crucial to further our understanding of natural
phenomena. Many systems of key interest and importance, in areas such as …

More than 100 years ago, Hertz succeeded in transmitting signals over a few metres to a
receiving antenna using an electromagnetic oscillator, thus proving the electromagnetic …

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 …

We present the design, fabrication and experimental implementation of surface ion traps
with Y-shaped junctions. The traps are designed to minimize the pseudopotential variations …
