Collaboration Drives Breakthrough in Scalable Quantum Processor Development
Chipmaker GlobalFoundries (GF) and UK-based quantum computing company Quantum Motion have announced a partnership to advance quantum processors using a scalable silicon platform. Leveraging their combined expertise, the companies aim to bridge the gap between quantum research and industrial-scale production.
In a joint statement, the firms revealed that GF has fabricated a silicon chip designed by Quantum Motion. The chip is claimed to be “at least 100 times faster than the current state of the art,” showcasing a significant leap in quantum computing capabilities.
Cutting-Edge Quantum Processor Design
Key Features of the New Quantum Chip
The newly developed quantum chip integrates an array of 1,024 quantum dots within an area of less than 0.1 square millimeters. This design enables rapid validation in under five minutes, demonstrating unparalleled efficiency.
Fabrication on the 22FDX Platform
The chip was manufactured using GF’s 300mm 22FDX platform, which offers:
- Power-efficient Edge processing
- System-on-chip integration
- Temperature capabilities of 1 Kelvin (-272.15°C/-457.87°F) and below
Additionally, the 22FDX platform includes back gate bias capability, which facilitates cryogenic tuning and control—a critical factor for optimizing quantum computing operations.
