    "abstract": "Recently Levy has shown that quantum computation can be performed using an\nABAB.. chain of spin-1/2 systems with nearest-neighbor Heisenberg interactions.\nLevy notes that all necessary elementary computational `gates\u0027 can be achieved\nby using spin-resonance techniques involving modulating the spin-spin\ninteraction strength at high frequency. Here we note that, as an alternative to\nthat approach, it is possible to perform the elementary gates with simple,\nnon-oscillatory pulses.",
