Surface-state electrons on liquid helium, localised in quantum dots, have been proposed as condensed matter qubits. Several groups have now demonstrated experimentally that small numbers of electrons, including a single isolated electron, can be held in electrostatic traps above the surface of superfluid helium. A potential well is created using microfabricated electrodes in a 3 – 5 mm diameter pool of helium. Electrons are injected into the trap from an electron reservoir on a helium microchannel. They are individually detected using a superconducting single-electron transistor (SET) as an electrometer. Recent results and new devices for an electron array will be presented.
