Tunable Nongeometric Phase Gates for Two Hot Ions via Adiabatic Evolution of Dark States

我们建议为为二实现非几何的阶段门的一个计划经由黑暗状态的断热的经过套住离子。在操作期间，震动的模式仅仅几乎激动，这样计划对加热感觉迟钝。而且，自从离子总是处于电子地面状态，自发的排放被压制。计划对参数的小变化是柔韧的，并且有条件的阶段是悦耳的。

We propose a scheme for implementing nongeometric phase gates fbr two trapped ions via adiabatic passage of dark states. During the operation, the vibrational mode is only virtually excited, thus the scheme is insensitive to heating. Furthermore, the spontaneous emission is suppressed since the ions are always in the electronic ground states. The scheme is robust against small fluctuations of parameters, and the conditional phase is tunable.
