A Bradbury-Nielson gate (BNG) includes a set of evenly spaced, co-planar, and parallel wires. The wires alternate in a repeating ABAB pattern, where all of the A wires are electrically connected to each other, all of the B wires are electrically connected to each other, and the set of A wires is electrically isolated from the set of B wires. Improved fabrication of Bradbury-Nielson gates is provided based on two key ideas. The first key idea is the use of wire positioning template surfaces having wire insertion features with enhanced spacing. Wire insertion features having enhanced spacing allow for non-microscopic assembly of finely spaced wire arrays. The second key idea is the use of two template surfaces, each having wires spaced by twice the eventual gate wire spacing. The use of two template surfaces facilitates making the alternating electrical contact required for a BNG.
