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…
