在热腔中,基于两原子的相互作用提出一个实现二量子比特Grover量子搜索算法的方案.在强经典场的作用下,取消了演化算符中依赖光子数的部分,因此方案不受热腔影响.该方案虽然简单但可能是扩展更为复杂的量子算法的重要步骤.

A scheme to implement the two-qubit Grover quantum search algorithm based on two-atom interaction in a thermal cavity has been proposed. The photon-number-dependent parts in the evolution operator are canceled with the assistant of a strong classical field. Thus the scheme is immune to the thermal field. The present scheme is simple but may be a key step to scale more complex quantum algorithms.
