Quantum Computer in the Solid State
Logo of Globalfoundries


GLOBALFOUNDRIES Fab 1 in Dresden, with its two state-of-the-art manufacturing facilities Module 1 (previously Fab 36) and Module 2 (previously Fab 38), an investment volume of more than €12 Billion since 1996 and currently more than 3000 highly qualified engineers, technicians and specialists, is the lead site for 22FDX of the company newly founded in 2009. The two existing semiconductor plants (or "modules") and the production expansion in the so-called "annex" are among the most productive and modern worldwide. The company manufactures high-performance microelectronic products in the innovative 55nm to 22nm technologies for a wide range of global customers and end-use applications on approximately 52,000m² of production space.

Role within QSolid

The aim of the research project is to create a cryogenic platform based on Globalfoundries 22FDX fully depleted silicon-on-insulator (FD-SOI) technology to enable highly integrated circuits for driving and reading out the quantum bits (Q-bits) developed in the QSOLID joint project. Particular technical aspects here are, on one hand, the expected heat sensitivity of the quantum processing unit (QPU) and, on the other hand, a very high integration density. The aspect of partial and full integration of different functions is a focus topic in order to enable technical scalability of the overall system. Scalability is generally considered to be an important prerequisite for the creation of a general-purpose and fault-tolerant quantum computer.

Our vision for QSolid

GF’s mission is to enable the use of GF’s advanced technologies such as 22FDX for general quantum computing, and position itself as leader in this emerging performance computing field.
