Ge is an appealing candidate for spin systems since it is largely compatible with the industrial manufacturing processes for semiconductors used throughout the world. Ge has recently received significant attention in the research community.
Ge and Ge/SiGe can facilitate the growth of quantum wells on silicon substrates or other Silicon-Germanium heterostructures. Ge/SiGe QD systems could also be combined in a scalable architecture to implement QPUs.
A quiet quantum environment, fast all-electrical qubit manipulation and controllable couplings are necessary ingredients for a scalable QPU architecture.

Hallbars are heterostructure field effect transistors that help us to understand material properties like carrier density and mobility.
They are fabricated in a nanofabrication facility.
A new analog quantum emulation scheme that improved on the time complexity of measuring a state, using a pair of sinusoidal sources to model n superimposed states. Read the paper.
A 48 DC line, 8 RF line chip carrier PCB designed for facilitating experiments at cryogenic temperatures. Open sourced on GitHub.
This AtTiny flasher allowed me to scale up my production of Leadme Inc. wearable hardware prototypes, which relied on our firmware to be installed on AtTiny microcontrollers.
The AtTiny-powered Leadme wearable device connected via bluetooth to the Android mobile app and recognized handshakes using an accelerometer.
An algorithm matched shakes by time and rhythm to auto-connect users in the social media platform.
