Abstract:

This paper exploits one optimized unitary operator to prepare a type of highly entangled state of multiple qubits—cluster state. Based on optimal control theory, the duration of optimized unitary operator has been shortened due to the application of a series of non-selective pulse. We experimentally implemented the optimized unitary operator on a NMR spectrometer. By firstly generating a pseudo-pure state, a three-qubit cluster state was produced by applying the optimized unitary operator. Our experimental results show the feasibility of the optimized unitary operator.

Key words: NMR, cluster state, quantum computation
