Quantum state engineering in arrays of nonlinear waveguides

David Barral, Mattia Walschaers, Kamel Bencheikh, Valentina Parigi, Juan Ariel Levenson, Nicolas Treps, Nadia Belabas

摘要:

在目前寻求有效和实验可行的平台,实现多模压缩和纠缠在连续变量制度,我们支持和补充我们的结果产生的通用多模纠缠和集群状态的非线性波导阵列提出的Barral等人,Phys. Rev. Appl. $\bf{14}$,044025(2020)。我们提出了详细的推导方程,描述通过这个系统的光的传播,然后我们专注于参数制度,这些方程可以解析求解。这些解析解为量子态的广阔前景建立了直观的认识,这些量子态可以通过激活泵浦、耦合和测量方案来获得。此外,我们展示了所获得的见解,通过使用一个确定的分析解决方案来展示空间线性集群状态的生成,优化和可扩展性。

英文摘要:

In the current quest for efficient and experimentally feasible platforms for implementation of multimode squeezing and entanglement in the continuous variable regime, we underpin and complement our results on the generation of versatile multimode entanglement and cluster states in nonlinear waveguide arrays presented by Barral et al., Phys. Rev. Appl. $\bf{14}$, 044025 (2020). We present detailed derivations of the equations that describe the propagation of light through this system, and then we focus on parameter regimes where these equations can be solved analytically. These analytical solutions build an intuition for the wide landscape of quantum states that are accessible through the activation of pumping, coupling and measurement schemes. Furthermore, we showcase the acquired insights by using one of the identified analytical solutions to exhibit the generation, optimization and scalability of spatial linear cluster states.
