Strong coupling of a microwave photon to an electron on helium
G. Koolstra, E. O. Glen, N. R. Beysengulov +6
Electrons bound to the surface of superfluid helium have been proposed for scalable charge and spin-based quantum computing. However single electron quantum measurement in this sys…

High-impedance resonators for strong coupling to an electron on helium
G. Koolstra, E. O. Glen, N. R. Beysengulov +9
The in-plane motion of an electron on helium can couple to superconducting microwave resonators via electrical dipole coupling, offering a robust and rapid readout scheme. In previ…

Sensing and Control of Single Trapped Electrons Above 1 Kelvin
K. E. Castoria, N. R. Beysengulov, G. Koolstra +6
Electrons trapped on the surface of cryogenic substrates (liquid helium, solid neon or hydrogen) are an emerging platform for quantum information processing made attractive by the…
