Query: Extremely efficient clocked electron transfer on superfluid helium   Unprecedented transport efficiency is demonstrated for electrons on the
surface of micron-scale superfluid helium filled channels by co-opting silicon
processing technology to construct the equivalent of a charge-coupled device
(CCD). Strong fringing fields lead to undetectably rare transfer failures after
over a billion cycles in two dimensions. This extremely efficient transport is
measured in 120 channels simultaneously with packets of up to 20 electrons, and
down to singly occupied pixels. These results point the way towards the large
scale transport of either computational qubits or electron spin qubits used for
communications in a hybrid qubit system.
