Abstract
Experiments are in progress to measure and control the quantum states of surface state electrons on liquid helium, both individually and in arrays, for potential use as qubits. This requires the fabrication of novel electronic devices using microstructured substrates, the excitation of Rydberg states using millimetric microwaves and the detection of individual electrons and their quantum states. This paper presents some preliminary experimental results.
