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 …

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 …

One of the most formidable challenges of scaling up quantum computers is that of control-
signal delivery. Today's small-scale quantum computers typically connect each qubit to one …

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 …

Scaling trapped-ion quantum computing will require robust trapping of at least hundreds of
ions over long periods, while increasing the complexity and functionality of the trap itself …

We present a new setup to sympathetically cool 115 In+ ions with 172 Yb+ for optical clock
