论文摘要
我们提出了一项协议，以实现具有两个计算原子和一个辅助原子的原子非绝热量子计算（NHQC）。在Rydberg Blockade的制度中分析了系统的动力学，并且通过反向工程设计了强大的激光脉冲，因此可以通过高保真度轻松实现量子门。此外，我们还研究了用主方程式使用耗散的进化。结果表明，可以通过测量辅助原子的状态来预见原子的衰减，如果辅助原子仍位于其rydberg州，则可以获得几乎完美的统一进化。因此，该协议可能有助于在耗散环境中实现NHQC。
We propose a protocol to realize atomic nonadiabatic holonomic quantum computation (NHQC) with two computational atoms and an auxiliary atom. Dynamics of the system is analyzed in the regime of Rydberg blockade, and robust laser pulses are designed via reverse engineering, so that quantum gates can be easily realized with high fidelities. In addition, we also study the evolution suffering from dissipation with a master equation. The result indicates that decays of atoms can be heralded by measuring the state of the auxiliary atom, and nearly perfect unitary evolution can be obtained if the auxiliary atom remains in its Rydberg state. Therefore, the protocol may be helpful to realize NHQC in dissipative environment.
