Ion Based Quantum Computing in Microfabricated Surface Traps
ORAL · Invited
Abstract
Trapped-ion-based quantum computers are rapidly progressing in terms of both algorithm complexity and qubit number. However, like all quantum processors, these machines are challenged by environmental and control noise. Fortunately, improvements to gate implementation and advancements in hardware design can mitigate many of our current noise sources. This talk will cover current work at Sandia National Laboratories that is focused on these developments. First, I will discuss how the Quantum Scientific Computing Open User Testbed (QSCOUT), a small quantum computer based on trapped-ion qubits at Sandia, has been used to accelerate progress in qubit control and noise mitigation. Secondly, I will talk about hardware changes, most notably advancements in ion trap design and integrated technologies, that will help address scaling beyond 100's of qubits.
