Fast coherent control of a charge qubit on solid neon with a spin-qubit-compatible resonator
Jun Wang, Yiran Tian, Ivan Grytsenko +7
Electrons floating in vacuum provide a clean platform for quantum information processing owing to their isolation from material defects. In particular, electrons on solid neon have…

Strong Coupling Between RF Photons and Plasmons of Electrons on Liquid Helium
Asher Jennings, Ivan Grytsenko, Thomas Giovansili +6
Plasmons, arising from the collective motion of electrons, can interact strongly with electromagnetic fields or photons; this capability has been exploited across a broad range of…

Probing the Quantum Capacitance of Rydberg Transitions of Surface Electrons on Liquid Helium via Microwave Frequency Modulation
Asher Jennings, Ivan Grytsenko, Yiran Tian +4
We present a method for probing the quantum capacitance associated with the Rydberg transition of surface electrons on liquid helium using radio-frequency (RF) reflectometry. Reson…
