Silicon Quantum Computing Pty Ltd

Silicon Quantum Computing (SQC) is an Australian technology company specializing in the development of scalable, error-corrected quantum computers using silicon-based spin qubits. Founded in 2017 and headquartered in Sydney, the company utilizes its proprietary atomic-scale manufacturing process, known as Precision Atom Qubit Manufacturing (PAQMan), to place phosphorus atoms within pure silicon wafers with 0.13 nanometer precision. This materials science-based approach allows SQC to produce qubits with high fidelity, exceptional stability, and low noise, enabling the creation of compact, high-performance quantum processors. The company maintains an integrated full-stack model, designing and manufacturing its own quantum processing units (QPUs) and classical control hardware in-house, which facilitates rapid design-test cycles and high-performance algorithmic execution.

SQC provides commercial solutions, including quantum-enhanced artificial intelligence via its Watermelon feature generator and analog quantum simulation through its Quantum Twins processors, which help customers gain insights into complex systems unattainable through classical computation. By manufacturing at the atomic scale, SQC aims to deliver efficient, deployable quantum systems that operate with minimal error. Its technology is designed for integration into existing customer environments, supported by long coherence times and industry-leading gate fidelities. The company’s work is intended for applications across diverse sectors such as finance, defense, transport, communications, energy, and pharmaceuticals, with a focus on providing measurable quantum advantage through a scalable and cost-effective solid-state platform.
