泄漏量子存储器之间的高保真态转移

High-fidelity State Transfer Between Leaky Quantum Memories

Daniel Soh, Eric Chatterjee, Matt Eichenfield

摘要:

我们推导出两个不同的量子存储块的最佳分析量子状态转移控制解决方案。采用量子网络理论的SLH形式主义描述,我们计算了系统种群的完整量子动力学,这导致了可达到的最高量子保真度的最佳解决方案。我们表明,对于两个光机械振荡器的机械模式作为量子存储器块的例子,它们的光模式和连接它们的波导通道可以用来实现量子态传输保真度为96%的现实参数,使用我们推导出的最优控制解决方案。定量地讨论了物理存储器参数中的本征损耗和非对称性的影响。

英文摘要:

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.
