• Equal1 successfully validates a commercial CMOS process utilizing GlobalFoundries' technology, marking a critical step toward scalable, silicon-based quantum technologies for spin qubits.
• The validation demonstrates the formation of multiple quantum dots with tunable tunnel coupling – a first in a commercial process.
• The ability to integrate quantum computing functionalities into a CMOS process opens the door to large-scale adoption.

Equal1, a global leader in silicon powered quantum computing, has announced a major milestone in quantum computing: the successful validation of a commercial CMOS process.

Jason Lynch, CEO of Equal1: "While some in the industry suggest that quantum computing is decades away, our work demonstrates that scalable quantum systems are closer than we thought. We're proving that quantum computing doesn't need to remain an elusive goal – it can align with the industrial strengths of today's semiconductor ecosystem to deliver meaningful results."

Equal1's monolithic chip contains 29 NMOS and PMOS quantum cells, each hosting linear quantum-dot arrays capable of supporting up to three tunnel-coupled quantum dots and charge sensor structures. Tested across a temperature range from 70 mK to 1.2 K, Equal1's quantum dot arrays have demonstrated robust performance and operational stability.

Dr. Elena Blokhina, Chief Science Officer at Equal1: "Unlike other approaches that depend on exotic materials and custom fabrication methods, Equal1's strategy is built on leveraging GlobalFoundries' industry-standard 22FDX FD-SOI silicon platform."

Ted Letavic, Corporate Fellow and Senior Vice President at GlobalFoundries: "The promising results by Equal1 show that GF's essential 22FDX technology is gaining momentum as a quantum platform. We look forward to partnering with Equal1 as they optimize their 22FDX designs to demonstrate further quantum milestones."
