The first generation of quantum computers are on the horizon, fabricated from quantum
hardware platforms that may soon be able to tackle certain tasks that cannot be performed or …

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 …

Trapped ions in radio-frequency traps are among the leading approaches for realizing
quantum computers, because of high-fidelity quantum gates and long coherence times …

Quantum processors based on linear arrays of trapped ions have achieved exceptional
performance, but scaling to large qubit numbers requires realizing two-dimensional ion …

Quantum information processing (QIP) has become a hot research topic as evidenced by S.
Haroche and DJ Wineland receiving the Nobel Prize in Physics in 2012. Various MEMS …

We explore the feasibility of implementing a small surface code with 9 data qubits and 8
ancilla qubits, commonly referred to as surface-17, using a linear chain of 171 Yb+ ions. Two …

A large qubit capacity and an individual readout capability are two crucial requirements for
large-scale quantum computing and simulation. As one of the leading physical platforms for …

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 …

The High Optical Access (HOA) trap was designed in collaboration with the Modular
Universal Scalable Ion-trap Quantum Computer (MUSIQC) team, funded along with Sandia …
