    "abstract": "Universal quantum information processing requires single-qubit rotations and\ntwo-qubit interactions as minimal resources. A possible step beyond this\nminimal scheme is the use of three-qubit interactions. We consider such\nthree-qubit interactions and show how they can reduce the time required for a\nquantum state transfer in an XY spin chain. For the experimental\nimplementation, we use liquid-state nuclear magnetic resonance (NMR), where\nthree-qubit interactions can be implemented by sequences of radio-frequency\npulses.",
