Progress and perspectives on the control of single electrons on helium

Electrons trapped above the surface of liquid helium (eHe) hold immense promise as a qubit candidate due to their inherent scalability and the long predicted coherence time of single spins in vacuum. In this talk we discuss EeroQ Quantum Hardware's approach towards addressing design and control challenges for single eHe devices. Specifically, we provide an overview of our progress designing single electron devices that integrate helium microchannels, dc control lines, and planar superconducting resonators. We also discuss our approach towards enhanced control of the in-plane motional states of eHe. Our efforts to address device fabrication challenges, mitigate noise sources, and boost the coupling to single electrons pave the way for future eHe-based quantum processors.
