Foundry

Quantum Computing Inc. operates a quantum photonic chip manufacturing facility in Tempe, Arizona, producing Thin Film Lithium Niobate (TFLN) chips for quantum computing, machine learning, and sensing applications. The company’s photonic foundry represents critical infrastructure for developing integrated quantum photonic systems. By combining quantum photonics fabrication with quantum computing systems development, QCI aims to accelerate commercialization of photonic quantum technologies for entropy computing and photonic optimization applications.

2025 Developments: The company continues its quantum technology initiatives throughout 2025. Focus remains on advancing core technologies and expanding market presence. Ongoing development activities position the company for future growth in the quantum industry.

SEEQC is developing a digital quantum computing platform that combines classical and quantum technologies with its own chip foundry capabilities to address efficiency, stability, and cost challenges in quantum computing. The company’s unique approach integrates single flux quantum (SFQ) digital logic with superconducting qubits on the same chip, enabling co-located classical control electronics at cryogenic temperatures. SEEQC’s commercial quantum chip foundry in New York provides the infrastructure to manufacture these hybrid classical-quantum integrated circuits at scale.

SpinQ Technology is the first Chinese company to export superconducting quantum chips internationally, with complete in-house fabrication capabilities from chip design to packaging. The company projects delivery of a 100-qubit superconducting quantum computer system by the end of 2025. SpinQ operates its own quantum chip foundry in Shenzhen, representing China’s growing capabilities in sovereign quantum hardware manufacturing and positioning the company as a key player in global quantum computing supply chains.
