In this project, we set out to realize a complete description of nonlinear quantum processes involving microcavity polaritons. Such a description is given by a process matrix that maps every possible input state fed to the system to its corresponding output state. To construct this matrix, we will combine advanced spectroscopic techniques and theoretical modelling to realize nonlinear quantum process tomography – a technique known from quantum optics – and apply it to the specific challenges posed by semiconductor systems. In detail, we will fully characterize spontaneous polariton condensate formation, vortex formation, and the polariton optical parametric oscillator.

在这个项目中，我们致力于实现对包含微腔极化子的非线性量子过程的完整描述。这样的描述由过程矩阵给出，该过程矩阵将馈送到系统的每个可能的输入状态映射到其对应的输出状态。为了构建这个矩阵，我们将结合先进的光谱技术和理论建模来实现非线性量子过程层析成像-一种源自量子光学的技术-并将其应用于半导体系统带来的特定挑战。详细地，我们将充分描述自发极化激子凝聚体的形成，涡旋的形成，以及极化激子光学参量振荡器。
