提出了一个利用离子阱系统实现三比特量子控制相位门的方案.在这个方案里,只需对囚禁离子辅以单比特旋转操作并与激光发生共振相互作用便可实现三比特控制相位门.相比其他文献中控制相位门的实现方案,此方案的优势在于所用的步骤更为简便易行.另外,此方案不需要任何测量.
A scheme for implementing three-qubit quantum controlled phase gate is proposed in the trap-ion system.It only requires the resonant interaction between trapped ions and lasers.Compared to the scheme in other papers,the steps needed are much less.In addition,the scheme doesn't need any type of measurement.
