Problem
Current quantum computing hardware struggles to scale beyond a few hundred qubits due to limited qubit density, high interconnect overhead, and reliance on specialized fabrication processes, which hampers the ability to tackle real‑world problems that require fault‑tolerant, large‑scale quantum processors.
Solution
Arque Systems delivers a silicon‑based quantum processor that encodes information in electron spins within a standard CMOS substrate. Their patented qubit architecture provides orders‑of‑magnitude higher qubit density while preserving high coherence and fast gate operations. By integrating on‑chip cryogenic control electronics, the platform reduces wiring complexity and enables independent, low‑latency control of each qubit. Leveraging mature semiconductor manufacturing lines, the solution offers a cost‑effective path to millions of qubits, positioning it for fault‑tolerant quantum advantage on computational chemistry, materials science, and cryptography workloads.
Target Audience
Primary customers are quantum research institutions, enterprise R&D labs, and cloud quantum service providers that require high‑density, fault‑tolerant processors for large‑scale simulations and algorithm development.
