講演概要
Electrons bound to superfluid helium have been suggested as qubits, utilizing either either a motional state (in or perpendicular to the plane of the helium surface) or an electron's spin as the qubit. In this talk I will largely concentrate on spin qubits. The spin is naturally capable of relatively long coherence, and in the vacuum above a helium surface the spins are predicted to have particularly long coherence, as well as being highly mobile. One anticipated advantage of these qubits is that the quantum gates will not require individual tuning, and thus be easier to scale to large systems. However, those gates will require confining the electrons into small areas, and thus the helium film supporting them must be thin. I will present recent data on electron transport on thin helium films, single-electron quantum dots, and high electron densities where overlap of wave functions likely occurs.
