摘　　要：利用纯几何操作,提出腔场中的氮空穴色心作为量子比特实现几何量子计算的方案.在暗态子空间中,选取合适的闭合演化回路,可以构造出单比特和双比特控制相位门.因此,该文提出了一种很有前景的实现容错量子计算的方案.A scheme to realize quantum computation with nitrogen-vacancy centers in a cavity was proposed,which was based solely on geometric manipulations of the system.It was shown that both single-qubit and two-qubit controlled phase gates could be constructed with appropriate cyclic evolutions within the degenerate dark states subspace of the system.Therefore,the scheme provided a promising way of implementing robust quantum computation.
