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 throughput of device testing 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 milliKelvin temperatures necessary for quantum operations. We also discuss recent advances in device design that aim to improve the performance of Si/SiGe quantum dot-based qubits.
