    "abstract": "The three-qubit conditional swap gate(Fredkin gate) is a universal gate that\ncan be used to create any logic circuit and has many direct usages. In this\npaper, we experimentally realized Fredkin gate with only three transition\npulses in solution of alanine. It appears that no experimental realization of\nFredkin gate with fewer pulses has yet been reported up to now. In addition,\nthe simple structure of our scheme makes it easy to be implemented in\nexperiments.",
