"signal zig-zags through/ around holes in silicon nitride membrane perforated with many triangular 10 mm holes, with 1 out of a million signals lost... current fluctuation amplitude similar that in electronic circuits, but the later decreases about 100K times faster... quantum computers/ bio-sensors which depend on super-precise signal transfer"
