Silicon Quantum Computing (SQC; Sydney, Australia; www.sqc.com.au), a leader in quantum
computing and quantum machine learning, today announced the launch of Quantum Twins, an
application-specific quantum simulator designed to accelerate molecule and materials
discovery. Built utilizing the company’s atomic-scale semiconductor manufacturing process,
Quantum Twins showcases the exceptional precision and already-achieved scalability of SQC’s
full-stack approach to quantum computing.
Quantum Twins are comprised of large arrays of qubit registers (quantum dots) patterned on pure
silicon with 0.13 nanometer (atom level) accuracy. This exquisite precision enables SQC to
create custom chips – Quantum Twins – that physically encode direct replicas of the physical
systems and chemical interactions that customers wish to analyse and understand.
This world-first product provides a pathway to simulation of quantum systems that is impossible
for classical computers. Quantum Twins provide an enhanced understanding of quantum
interactions. Analysing magnetism, atomic interaction and superconductivity at this scale will
pave the way for novel information storage, low power electronics and broad materials discovery.
Details on the scientific foundation of this platform were published today in Nature, a system
including 15,000 qubit registers.
The launch follows a period of rapid expansion in SQC’s manufacturing capabilities. In November
2025, the company demonstrated the ability to pattern 250,000 qubit registers in just eight hours,
de-risking the required manufacturing yields and volumes needed to deliver commercial-scale,
fault-tolerant quantum computers. As a full-stack company, SQC can design, produce and test
new quantum chips in under a week. It’s one of the many key advantages of the company’s 14|15
platform in the race to deliver the world’s first commercial scale quantum computer.
SQC’s Founder and CEO, Michelle Simmons, said: “Quantum Twins represents a window into
the quantum world that customers can use for materials discovery today. The enabler is that we
can engineer hundreds of thousands of qubit registers with atomic precision. It’s an incredible
achievement in semiconductor manufacturing with sub-nanometer accuracy.”
SQC’s Chair and former ARM CEO, Simon Segars, added: “Expanding our product offering with
the launch of Quantum Twins brings SQC’s atomic-scale advantage to the global materials and
chemistry sectors. Having demonstrated commercial success with our quantum machine
learning system, Watermelon, SQC’s latest offering is a definitive signal of our world leading
manufacturing precision and scalability.”
SQC debuted its multi-qubit, multi-register processor last month with industry-leading fidelities
up to 99.99% and performance that improves as the system scales. The company recently
progressed to Stage B of DARPA’s Quantum Benchmarking Initiative and its quantum machine
learning system, Watermelon, is already delivering impact across a variety of sectors including
telecommunications and defense.
SQC is at the forefront of global efforts to build a commercial-scale quantum system. Leveraging over 25 years of technological excellence and delivery, SQC’s proprietary machines and processes allow the company to see and control matter atom-by-atom.
Quantum Twins are now available via direct contract with SQC.
