"atomtronic circuits... waves of ultracold atoms guided and manipulated by optical and/or magnetic fields form advanced transistors and diodes... manipulate BEC's shape... atomtronic circuits... like atomtronic superconducting quantum interference devices... neutral atoms result in less information loss...change features of device more easily... complex atomtronic circuits... highly controllable and easily reconfigurable quantum sensors capable measuring tiny magnetic fields otherwise immeasurable"
