SQC’s “Quantum Twins”: A New Horizon in Quantum Simulation
Silicon Quantum Computing (SQC) has unveiled “Quantum Twins,” a platform built on 15,000-qubit registers patterned on pure silicon with atomic precision. The system is designed to represent and simulate large quantum systems directly on a silicon substrate, giving researchers a new route to model many-body physics and molecular electronic structure at scales that were previously out of reach for classical methods.
The Breakthrough: 15,000 Qubits on Silicon
The headline technical achievement is the fabrication of 15,000 qubit registers on pure silicon with placement controlled at near-atomic length scales. Silicon is attractive because it leverages decades of semiconductor manufacturing know-how, offers compatibility with CMOS processes, and can reduce device variability when qubits are positioned precisely. Atomic precision in qubit placement reduces parameter spread across devices, which helps lower decoherence and systematic error sources that often limit large-scale experiments.
Unlocking Complex Quantum Systems
Quantum Twins aims to map physical Hamiltonians more faithfully than coarse-grained classical approximations. With larger qubit registers and tighter control over qubit properties, simulations can represent bigger Hilbert spaces and capture strongly correlated phenomena, electron correlation in molecules, and emergent effects in materials. For quantum chemistry this means better estimates of binding energies, reaction pathways, and excited states. For materials science it supports studies of superconductivity, magnetism, and defect physics with improved fidelity.
Practically, SQC’s platform can accelerate materials design cycles and the computational stages of drug discovery by offering high-resolution quantum models that feed into experimental and classical workflows. Integration with variational algorithms and hybrid quantum-classical toolchains will be important for translating raw qubit capacity into usable scientific results.
Outlook for Quantum Modeling
SQC’s Quantum Twins signal a push toward scalable, silicon-based quantum simulation that connects fabrication precision to scientific modeling power. While challenges remain in error correction, software maturity, and application-specific integration, access to large, uniform qubit registers is a notable step for researchers seeking to model complex quantum physics and chemistry at new scales.
