论文摘要
我们为两个不同的量子存储器块提供了最佳的分析量子状态转移控制解决方案。我们采用了量子网络理论的SLH形式主义描述，我们计算了系统种群的完整量子动力学，从而为最高的量子保真度提供了最佳解决方案。我们表明，在例如，两个光机电振荡器的机械模式充当量子内存块，它们的光学模式和连接它们的波导通道可用于实现使用我们派生的最佳控制解决方案的量子状态传输忠诚度为96％。定量讨论了物理记忆参数中内在损失和不对称的影响。
We derive the optimal analytical quantum-state-transfer control solutions for two disparate quantum memory blocks. Employing the SLH formalism description of quantum network theory, we calculate the full quantum dynamics of system populations, which lead to the optimal solution for the highest quantum fidelity attainable. We show that, for the example where the mechanical modes of two optomechanical oscillators act as the quantum memory blocks, their optical modes and a waveguide channel connecting them can be used to achieve a quantum state transfer fidelity of 96% with realistic parameters using our derived optimal control solution. The effects of the intrinsic losses and the asymmetries in the physical memory parameters are discussed quantitatively.
