摘要:

我们研究了在一种过程中所需的时间依赖拉比频率的形式,该过程能够通过外部场连续地将系统与环境噪声解耦,从而保护原子三能级系统(qutrit)上量子门的作用。我们考虑了多种模拟来保护量子门模型的作用,包括随机选择的门模型。我们认为,当前实验条件已经能够满足对拉比频率的要求。我们还研究了从一个门操作到另一个门操作的过渡,包括保护三能级系统存储态。最后,我们将我们的方法应用于保护一种能够区分三个元素排列奇偶性的算法的执行免受噪声影响。

英文摘要:

We investigate the form required for the time-dependent Rabi frequencies involved in a procedure capable to protect the action of quantum gates on an atomic qutrit by means of external fields continuously decoupling the system from the environmental noise. Several simulations are considered to protect the action of quantum-gate models, including randomly chosen ones. We argue that the requirements for the Rabi frequencies could be nowadays experimentally met. We also investigate the transition from one gate operation to another, including protecting a qutrit memory state. We finally apply our methodology to protect from noise the application of an algorithm capable of distinguishing the parity of permutations of three elements.
