基于频率调制激光驱动的囚禁离子几何相位逻辑门
A scheme for the geometric phase logic gates based on trapped ions driven by frequency-modulated laser
【摘要】 为了避免激光相位的起伏对几何相位逻辑门保真度的影响,提出一种基于囚禁离子的量子几何相位逻辑门的新方案.该方案是利用一束频率调制的行波激光场作用于两个囚禁离子上实现的.它的优点有:操作简单,仅需一步就能实现,不灵敏于激光场的相位也不需要对囚禁离子进行个别寻址.
【Abstract】 To avoid the effect of phase fluctuation of laser on fidelity of the geometric phase logic gate,we propose a scheme for quantum geometric phase gate based on trapped ions. This scheme works by the interaction of the trapped ions with a frequency- modulation traveling wave light field. The advantages of the scheme include:it can work by one- step operation,it is insensive to the phase of the laser,and it does not require individual addressing.
