Quantum Computing

Superconducting qubits are electrical circuits made of superconducting materials that operate at extremely low temperatures. They are controlled using microwave pulses. Due to their compatibility with the prevailing processes in the semiconductor industry, they are one of the most promising technologies for quantum computers. Fraunhofer IPMS leverages its expertise in state-of-the-art, industry-compatible CMOS semiconductor manufacturing in the 300 mm wafer standard. Focus: Deposition, nanostructuring, electrical characterization, cryogenic control electronics, optimized metallization, and BeoL modules for superconducting qubits.

Here, the spin of an electron in a semiconductor device (e.g., silicon) serves as a qubit. Semiconductor-based qubits are a promising type of qubit for quantum computers because they are based on the same materials and manufacturing processes as conventional chips. By using known CMOS manufacturing methods, these qubits can potentially be miniaturized and integrated in large numbers. A key advantage is the ability to integrate the control electronics directly on the chip, which enables scalability and could facilitate the manufacture of larger and more powerful quantum computers.

Fraunhofer IPMS is participating by utilizing adapted processes from CMOS manufacturing. The focus is on using our state-of-the-art 300 mm CMOS cleanroom to provide technology improvements for scalable quantum computing.
