论文摘要
通过动态CASIMIR效应（DCE）进行了复杂量子状态生成的集成光子方法。这种方法提供了一种方案，可以通过微波炉（MW）和Terahertz（THZ）方案实现多明确的高维纠缠状态，这是通过在MW谐波中的调制与支持时间光学孤子的光学微孔子耦合的调制。 MW-resonator的各州从基态发展，从基态的虚拟光子中实现了现实光子。通过KERR诱导的光学微孔子折射率变化以及耗散性KERR Solitons（DKSS）的局部空间分布，对MW谐振器的周期性调节，使光子对生成和MW-W-W-W-函数偶联的局部空间分布启用。这允许在各种频谱中生成高度持久的多部分高维纠缠状态。提出的方法为混合集成平台铺平了道路，用于在MW和THZ方案中使用高度相干的超短光脉冲在单体集成平台中生成MW和THZ策略的多部分纠缠量（高维Qudits（高维Qud）。该体系结构可以充当纠缠的状态源，是利用从容忍计算到增强感应和传送的广泛量子协议的必要资源。
An integrated photonic approach for complex quantum state generation through dynamical Casimir effect (DCE) is demonstrated. This approach provides a scheme to realize multipartite high-dimensional entangled states in the microwave (MW) and terahertz (THz) regimes, through the modulation in a MW-resonator coupled to an optical microresonator supporting temporal optical solitons. The states at the MW-resonator evolve from the ground state, realizing real-photons from the virtual photons at the ground state. The periodic modulation of the MW-resonator through a Kerr-induced refractive index change in the optical microresonator, along with the localized spatial distribution of the dissipative Kerr solitons (DKSs), enables photon-pair generation and inter-mode coupling at the MW-resonator. This allows generating highly persistent multipartite high-dimensional entangled states in a wide range of spectrum. The proposed approach paves the way for a hybrid integrated platform for generation of multipartite entangled qudits (high-dimensional qubits) at the MW and THz regimes using highly coherent ultra-short optical pulses in a monolithic integrated platform. This architecture can act as an entangled state source, as a necessary resource for exploiting a wide range of quantum protocols from fault-tolerant computing to enhanced sensing and teleportation.
