JuliaCon 2025

DeviceLayout.jl is a package for computer-aided design (CAD) of quantum integrated circuits, supporting schematic-driven design, 2D geometry rendering, and the construction and meshing of 3D models. We show how it can be used for layout of a superconducting quantum processor, and we highlight its use for design and simulation with Palace, an open-source 3D finite element solver for computational electromagnetics.

At the AWS Center for Quantum Computing (CQC), we are working towards fault-tolerant quantum computers capable of solving problems of commercial and scientific importance that are beyond the reach of today’s conventional computers. The CQC recently announced a new quantum chip, Ocelot, designed for quantum error correction with overhead reduced by up to 90%. In this talk, we will introduce the CQC, our approach to quantum computing, and technologies (including Julia) we used to design Ocelot.
