High-volume manufacturing of semiconductors has enabled the integrations of billions of transistors on a single chip. Intel leverages this expertise to address engineering challenges in the scale-up of quantum computers. In this talk, we discuss how silicon spin qubits are fabricated in a state-of-the-art CMOS 300 mm fabrication line. The qubits are comparable in size to a transistor, and are highly coherent. Further on, advancements in the measurement infrastructure, such as a 300 mm wafer probing tool operating at 1.6 Kelvin, are shown. Lastly, we will discuss how control electronics operating at cryogenic temperatures can address the interconnect challenge all solid state quantum technologies face.
Bio: Florian Luthi is a quantum computing engineer at Intel. He received his PhD in Physics from Delft University of Technology where he worked on combining superconducting transmon qubits with semiconducting nanowires. He studied the coherence properties of these circuits, and their behavior in a magnetic field. Florian joined Intel in 2019 to work on the quantum computing program where he is heading the development of measurement and calibration software to optimally control quantum circuits.
