SQC launches Quantum Twins for physics and chemistry simulation

Silicon Quantum Computing (SQC) has introduced Quantum Twins, a specialized quantum simulator designed to expedite the discovery of molecules and materials. Utilizing atomic-scale semiconductor manufacturing, this platform is engineered to simulate quantum physics and chemistry in ways that surpass the capabilities of classical computers.

For readers of eeNews Europe, this announcement holds significance as it bridges advanced semiconductor fabrication with practical quantum simulation applications. It showcases the progression of atomic-precision manufacturing from experimental demonstrations in laboratories to tools that are commercially viable for research in materials, electronics, and energy.

Atomic-Precision Quantum Simulation

Quantum Twins are constructed using extensive arrays of qubit registers, known as quantum dots, that are precisely patterned on pure silicon with an accuracy of 0.13nm at the atomic level. SQC asserts that this level of precision enables the development of customized chips that physically replicate the systems and chemical interactions customers wish to analyze.

This innovative approach transforms the chip itself into a model of the desired quantum system. By encoding interactions like magnetism, atomic bonding, and superconductivity directly, Quantum Twins facilitate simulations that are beyond the reach of even the most powerful classical computers. SQC suggests that this capability paves the way for novel concepts in information storage, low-power electronics, and extensive materials exploration.

The scientific underpinning of the platform was recently published in Nature, detailing a system comprising 15,000 qubit registers. SQC positions this as a groundbreaking demonstration of quantum simulation on such a scale using silicon-based qubits.

Manufacturing Scale and Full-Stack Control

This launch follows a rapid expansion in SQC’s manufacturing capabilities. In November 2025, the company showcased the ability to pattern 250,000 qubit registers within eight hours, a milestone that mitigates risks associated with yields and volumes necessary for fault-tolerant quantum computers at a commercial scale. As a comprehensive player, SQC claims it can design, fabricate, and test new quantum chips in less than a week using its 14|15 platform.

Michelle Simmons, the founder and CEO of SQC, remarked, “Quantum Twins provides a glimpse into the quantum realm that customers can leverage for materials discovery today. The key lies in our ability to engineer hundreds of thousands of qubit registers with atomic precision. This achievement in semiconductor manufacturing with sub-nanometer accuracy is truly remarkable.”

Simon Segars, the Chair of SQC, added, “Expanding our product portfolio with the introduction of Quantum Twins brings SQC’s atomic-scale advantage to the global materials and chemistry sectors. Following the successful commercial deployment of our quantum machine learning system, Watermelon, this latest offering from SQC underscores our unparalleled precision and scalability in manufacturing.”

From Benchmarking to Availability

SQC recently unveiled a multi-qubit, multi-register processor with reported fidelities reaching up to 99.99%, showcasing improved performance as the system scales. The company has progressed to Stage B of DARPA’s Quantum Benchmarking Initiative, while its Watermelon quantum machine learning system is already in use across telecommunications and defense sectors. Quantum Twins are now accessible through direct contracts with SQC.
