"particle’s velocity and position collectively allow it to embody a unique and unambiguous sequence of states... latter circumstance is key to reversibility and thus low dissipation... consist of loops of superconducting material interrupted by structures called Josephson junctions (JJs), where a thin layer of a nonsuperconducting material is interposed between two superconductors... information in JJ circuits is usually encoded in the direction of their so-called supercurrent’s circulation"
