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…

A Hermetic On-Cryostat Helium Source for Low Temperature Experiments

K. E. Castoria, H. Byeon, J. Theis +7

We describe a helium source cell for use in cryogenic experiments that is hermetically sealed on the cold plate of a cryostat. The source cell is filled with helium gas…

Five-second coherence of a single spin with single-shot readout in silicon carbide

Christopher P. Anderson, Elena O. Glen, Cyrus Zeledon +11

An outstanding hurdle for defect spin qubits in silicon carbide (SiC) is single-shot readout - a deterministic measurement of the quantum state. Here, we demonstrate single-shot re…
