SQC Launches Quantum Twins Simulator and Reports 15,000-Qubit Register Fabrication Silicon Quantum Computing (SQC) has announced the launch of Quantum Twins™, an application-specific analogue quantum simulator designed for molecular and materials discovery. The platform is based on the fabrication of large-scale 2D arrays consisting of 15,000 atom-based quantum dots patterned on pure silicon with 0.13-nanometer (atomic-level) precision. This technical milestone, detailed in a new study published in Nature, utilizes scanning tunneling microscope (STM) hydrogen lithography to physically encode direct replicas of chemical interactions and physical systems that are computationally intractable for classical hardware. The scientific foundation of the platform involves simulating a Mott–Anderson metal–insulator (MI) transition on a 100 × 150 square lattice. By varying the inter-dot separation a from 7.2 nm to 17.1 nm, SQC researchers demonstrated independent control over the on-site interaction energy U (20.63 ± 0.94 meV) and the inter-dot tunnel coupling t (0.10 meV to 1.54 meV). Magneto-transport measurements of these arrays showed the effective interaction strength U/t scaling from 14 to 203, enabling the observation of correlated electron physics and signatures of Fermi-surface reconstruction. In parallel with the simulator launch, SQC reported a manufacturing throughput of 250,000 qubit registers in eight hours. This benchmark is intended to address manufacturing yields and volumes required for commercial-scale, fault-tolerant systems. The company’s 14|15 platform integrates this atomic-scale manufacturing with a full-stack approach, enabling the design, production, and testing of new quantum chips within a one-week cycle. This capability supports the transition from individual laboratory demonstrators to industrial-scale semiconductor fabrication. The launch follows recent technical results for SQC’s digital quantum processors, which achieved fidelities between 99.10% and 99.99% on an 11-qubit atom processor. That system utilized electron exchange interaction (J ≈ 1.55 MHz) to link distant spin registers, maintaining high-fidelity entanglement as qubit counts increased. Nuclear spin coherence times (T2Hahn) for these devices were recorded between 3 ms and 660 ms, supported by advanced refocusing protocols and the use of isotopically purified silicon-28. SQC’s commercial operations currently include the deployment of rack-mounted systems for the Australian Defence sector and the use of its Watermelon quantum machine learning system by Telstra. The company has progressed to Stage B of DARPA’s Quantum Benchmarking Initiative, focusing on the validation of its silicon modality for large-scale utility. Quantum Twins is now commercially available via direct contract, targeting research in magnetism, superconductivity, and low-power electronics.
