We propose a scheme for quantum geometric computation on a fiber-cavity-fiber system, in which two atoms are located in two single-mode cavities, respectively, connected with each other by optical fiber. This scheme not only has the feature of virtual excitation of photons in the cavity quantum electrodynamics (CQED) that can reduce the effect of decay effectively but also has the advantage of geometric phase to withstand noises due to its built-in noise-resilience feature and robust merit. Specifically, our proposal combined with optimized-control-technology (OCT) can reduce gate operation error by adjusting the time-dependent amplitude and phase of the resonant field which further enhances the robustness of the quantum operation. The robustness against decoherence is demonstrated numerically and the scheme may be applied in the remote quantum information processing tasks and quantum computation.

交换虚拟光子的腔-原子系统中基于优化控制技术的分布式几何量子计算

我们提出了一种在光纤-腔-光纤系统上进行量子几何计算的方案，其中两个原子分别位于两个单模腔中，并通过光纤相互连接。该方案不仅具有在腔量子电动力学（CQED）中虚拟激发光子的特性，可以有效地减少衰变的影响，而且由于其内置的噪声弹性特性，还具有几何相位可承受噪声的优点。稳健的功绩。具体来说，我们的建议与优化控制技术（OCT）相结合，可以通过调整随时间变化的共振场幅度和相位来减少栅极操作误差，从而进一步增强量子操作的鲁棒性。
