【摘要】：基于絕熱捷徑技術(shù),我們提出了一個(gè)通過(guò)設(shè)計(jì)共振脈沖,僅用一個(gè)操作步驟便實(shí)現(xiàn)兩原子相位門(mén)的理論方案。我們討論了原子自發(fā)輻射和腔中光子泄漏對(duì)方案的影響,數(shù)值結(jié)果表明當(dāng)前方案對(duì)上面的兩種耗散效應(yīng)和試驗(yàn)參數(shù)的誤差都具有魯棒性。此外,本方案所需的演化時(shí)間非常短并且在整個(gè)演化過(guò)程中都不需要額外引入復(fù)雜的脈沖。因此,這個(gè)方案在當(dāng)前實(shí)驗(yàn)條件下是比較容易實(shí)現(xiàn)的。
[Abstract]:Based on the adiabatic shortcut technique, we propose a theoretical scheme for the realization of two atomic phase gates by designing resonance pulses and using only one operation step. The effects of atomic spontaneous emission and photon leakage in cavity on the scheme are discussed. The numerical results show that the current scheme is robust to the above two dissipative effects and the errors of experimental parameters. In addition, the evolution time of the scheme is very short and complex pulses are not needed in the whole evolution process. Therefore, this scheme is relatively easy to implement under the current experimental conditions.
