摘要

摘要得到了存在Kerr非线性时量子点与量子电磁场相互作用的混合系统动力学的解析解。发现了一种全新的相互作用机制。它为全二部系统和量子点激发提供了稳定的周期性重复动力学,伴随着完全和纯粹的复苏。这甚至在初始场态处于压缩真空时也能观察到。证明了相互作用子系统之间的周期强纠缠和完全解纠缠。所获得的状态为涉及这些混合系统的量子信息算法和光子-物质界面的发展奠定了基础。揭示了非高斯场态的形成。开发了控制和管理所考虑的子系统的纯状态和混合状态的特定特征的方法。

Quantum dots interacting with a non-classical field under Kerr-phase modulation as a resource for repeatable quantum algorithms
Abstract An analytical solution describing the dynamics of a hybrid system comprising an interacting quantum dot and a quantum electromagnetic field in the presence of Kerr nonlinearity is obtained. A completely new regime of interaction is found. It provides stable periodically repeating dynamics for the total bipartite system and for the quantum dot excitation, accompanied by full and pure revivals. This is even observed when the initial field state is in a squeezed vacuum. Periodical strong entanglement and full disentanglement between the interacting subsystems are demonstrated. The obtained regime forms the basis for the development of quantum information algorithms and photon–matter interfaces involving these hybrid systems. The formation of non-Gaussian field states is revealed. Methods to control and manage the specific features of the found pure and mixed states of the considered subsystems are developed.
