    "abstract": "We proposed a scheme to realize a controlled-NOT quantum logic gate in a\ndimer of exchange coupled single-molecule magnets, $[\\textrm{Mn}_4]_2$. We\nchosen the ground state and the three low-lying excited states of a dimer in a\nfinite longitudinal magnetic field as the quantum computing bases and\nintroduced a pulsed transverse magnetic field with a special frequency. The\npulsed transverse magnetic field induces the transitions between the quantum\ncomputing bases so as to realize a controlled-NOT quantum logic gate. The\ntransition rates between the quantum computing bases and between the quantum\ncomputing bases and other excited states are evaluated and analyzed.",
