Silicon Quantum Computing

Develops silicon quantum processors using phosphorus atoms placed in silicon with atomic precision, alongside quantum machine-learning and simulation products.

In inglese

Founded in 2017, Silicon Quantum Computing (SQC) was formed to commercialise quantum-computing technology developed at UNSW Sydney. Its founder and CEO is physicist Michelle Simmons; the company was established with support from Australian and New South Wales governments, UNSW, Telstra and Commonwealth Bank of Australia. SQC builds processors using phosphorus atoms placed in silicon, and develops integrated hardware, control systems and software. Its stated work spans quantum computing, quantum simulation and quantum machine-learning products. In June 2022, SQC announced an integrated circuit manufactured at atomic scale. In February 2025, it reported 98.9% accuracy running Grover’s algorithm without error correction. In December 2025, it reported a multi-qubit, multi-register processor result published in Nature. SQC describes its current work as developing analogue and error-corrected processors. Its products include Watermelon, a quantum feature generator for classical machine-learning workflows, and Quantum Twins, an analogue simulator for chemistry and materials design; it is also developing gate-based processors.
