H. Pothier et al., PASSING ELECTRONS ONE BY ONE - IS A 10-8 ACCURACY ACHIEVABLE, IEEE transactions on instrumentation and measurement, 42(2), 1993, pp. 324-330
We analyze the error mechanisms of the single electron pump with an ar
bitrary number of junctions. An upper bound for the error probability
is computed analytically at zero temperature. We show that a 10(-8) ac
curacy is achievable for devices with five or more junctions.
