How to Wire a 1000-Qubit Trapped-Ion Quantum Computer — Maciej Malinowski1, David Allcock1,2, •Clemens Matthiesen1, and Chris Ballance1,3 — 1Oxford Ionics, Oxford, UK — 2University of Oregon, Eugene, USA — 3University of Oxford, Oxford, UK
Scaling up quantum computers requires efficient signal delivery to the quantum processor (the "wiring" challenge). It is likely that integration of control electronics into the processor package will be necessary, but this process is heavily constrained by chip microfabrication and chip operation specifications. Here, we present our WISE (Wiring using Integrated Switching Electronics) architecture as an answer to the wiring question, where judicious integration of simple switching electronics into the ion trap chip is combined with parallel trap electrode control [1]. This significantly reduces the number of signal sources needed, such that a fully connected 1000-qubit trapped ion quantum computer might be operated using only ∼ 200 signal sources.
