    • More detailed requirements can be formulated with the aid of the results (Ref. 10). For jeneric wires QPS effects are small provided the parameter √s exceeds ∼10 nm (Refs. 10 and 12).

    • Within the framework of the mean field theory parity effect in single channel rings was discussed by K. Kang, Europhys. Lett. 51, 181 (2000) and by H.-J. Kwon and V. M. Yakovenko, Phys. Rev. Lett. 89, 017002 (2002). In such rings, however, QPS effects may entirely wipe out the supercurrent thus making the mean field approach obsolete.

    • Quantum fluctuations of φ can easily be suppressed, e.g., by choosing the ring inductance sufficiently small. Accordingly, the number of Cooper pairs passing through the contact should strongly fluctuate effectively suppressing electrostatic effects in the contact area.
