Silicon Quantum Computing Tech Stack

Full-stack quantum computing hardware manufacturer with atomic-precision chip fabrication

Technology, Information and Internet Sydney, NSW 51–200 employees Founded 2017 Privately Held

Silicon Quantum Computing manufactures quantum processors in-house at its Sydney facility using atomic-precision fabrication — a vertically integrated approach that lets the team design, test, and iterate chip designs weekly rather than quarterly. The tech stack is dominated by EDA tools (Cadence, Mentor Graphics, Altium) and FPGA-to-silicon workflows (Xilinx, Verilog, VHDL), reflecting a hardware-first, silicon-centric company. The hiring mix is heavily skewed toward senior engineers (16 of 30 active roles), with projects focused on cryo-CMOS chip development, analog circuit design, and automated test frameworks—signaling intense focus on yield, reliability, and scaling toward 100+ qubit processors.

About Silicon Quantum Computing

Silicon Quantum Computing designs and manufactures quantum computing chips using atomic-precision techniques developed by CEO Michelle Simmons, a materials scientist credited with creating the world's first single-atom transistor. The company operates a full-stack quantum system, including proprietary QML chips and molecular simulators, and has reported the highest algorithmic fidelities of any commercial quantum vendor. All manufacturing happens in-house in Sydney, enabling weekly design iterations and tight control over fabrication quality. The company has raised AU$283m to date and operates with a 70+ person engineering organization focused on cryo-CMOS integration, thermal management, and processor scaling.
