    "abstract": "We argue that the analog nature of quantum computing makes the usual design\napproach of constructing complicated logical operations from many simple gates\ninappropriate. Instead, we propose to design multi-spin quantum gates in which\nthe input and output two-state systems (spins) are not necessarily identical.\nWe outline the design criteria for such devices and then review recent results\nfor single-unit Hamiltonians that accomplish the NOT and XOR functions.",
