Using a polaron master equation approach, we investigate the cooperative two-photon resonance behavior between two modes of a field inside a semiconductor microcavity containing two quantum dots. The cooperative two-mode two-photon resonance occurs when two off-resonant quantum dots, initially prepared in exciton states, emit one photon in each cavity mode and deexcite simultaneously. Using this two-photon two-mode interaction, we demonstrate how to generate an entangled state of two qutrits (tripartite unit of quantum information). The bases for the qutrits are formed by the states of the cavity modes containing zero, one, and two photons. We also study the effect of exciton-phonon coupling on the entanglement and the probability of generating two-qutrit states, and explore the role of the phonon bath temperature.

由两个半导体量子点介导的声子诱导的相互作用和两个微腔模式之间的纠缠形成

使用极化子主方程方法，我们研究了包含两个量子点的半导体微腔内部场的两种模式之间的协同双光子共振行为。当最初以激子态制备的两个非共振量子点在每个腔模中发射一个光子并同时去激励时，就会发生协同双模双光子共振。使用这种双光子双模相互作用，我们演示了如何生成两个量子态（量子信息的三方单位）的纠缠态。量子态的基由包含零，一和两个光子的腔模的状态形成。我们还研究了激子-声子耦合对纠缠的影响以及产生两个量子态的可能性，并探讨了声子浴温度的作用。
