摘要
我们提出了一种在雷德堡原子中实现稳健最优概率量子克隆(PQC)的方案。为了增强 PQC 电路的稳健性,我们将非绝热整体量子计算(NHQC)方法与超稳健动态校正脉冲相结合。我们的数值模拟表明,我们的方案在去相干条件下实现了较高的克隆保真度,优于之前的方案。此外,我们的方法在抗去相干性和 X 误差方面表现出色。总之,我们的方法在鲁棒 PQC 方面大有可为。
Optimal Probabilistic Quantum Cloning in Rydberg Atoms Based on Dynamically Corrected Geometric Quantum Operations
We propose a scheme to realize the robust optimal probabilistic quantum cloning (PQC) in Rydberg atoms. To enhance the robustness of the PQC circuit, we combine the nonadiabatic holonomic quantum computation (NHQC) method with super-robust dynamically corrected pulses. Our numerical simulations show that our scheme achieves high cloning fidelities under decoherence better than those of the previous scheme. Moreover, our method demonstrates excellent performance against decoherence and the X error. Overall, our approach is promising for robust PQC.
