    • We would like to emphasize the difference between pumping and rectification. By definition a pump converts ac variations of the parameters of an unbiased system into a net dc current. On the other hand, rectification converts an ac bias into a dc current. The pumping electrical circuit that we discuss works in the absence of an ac bias, so our effect is that of pumping. A qualitative difference between pumping and rectification currents is that the average pumping current is proportional to the frequency, ω, while the dc current in an ac-biased-diode does not depend on the frequency.

    • We use the 4 leg version for controlled dephasing instead of the 3 leg model since this enables us to obtain perfect dephasing. (See remark in Ref. 22.)
