| 摘 要： | 提出一个基于压缩算符的非常规几何量子相位门的方案.在腔QED系统中,在强共振经典场驱动下,利用两个三能级原子与腔模的双光子相互作用,研究了两量子比特非常规几何量子相位门,发现它与腔模占有数有关,当腔模初始时处于真空态,这个方案对腔模衰变不敏感.

| Abstract: | A scheme is proposed for realizing unconventional geometric quantum phase gate originated from high-dimensional squeezed operators,which can be easily generalized to the physical system of Cavity QED.In the scheme,two-qubit g unconventional geometric phase gate is carried out by threes level atoms in a cavity,strongly drive by a resonant classical field.Under ideal condition,the resonant interaction in our scheme results in a short gating time. |
