(Invited) Integrating Classical Semiconductor Devices with Si/Sige Quantum Dots
Abstract
As semiconductor based quantum devices scale up from single to multiple qubits there is an increasing need to integrate classical semiconductor based devices to manage and generate control signals. We discuss progress on integrating field-effect transistors with planar quantum dot devices to achieve a high level of device throughput by creating on-chip multiplexers for our devices. Using the on-chip multiplexers we can overcome the challenge of the limited number of electrical connections available in a typical dilution refrigerator while still working at the milli-Kelvin temperatures necessary for quantum operations. Additionally, we report on recent work on gate designs for scaling up to multiple, coupled Si/SiGe qubits. In particular we discuss the design, fabrication and initial characterization of quadruple quantum dot devices.
