Macroscopic quantum state engineering and transport in polaritonic devices

该项目旨在展示量子态工程和半导体中混合光物质粒子的新型输运。这些粒子被称为激子-极化子，形成了延伸到微米的宏观量子态，并在可接近的尺度上显示出量子行为。它们从光（光子）和物质（激子）成分中继承了超快的速度和大的非线性，因此代表了下一代光电子学的有吸引力的平台。本项目旨在使我们能够在宏观尺度上探索基本的量子多体物理，并设计和测试具有信息存储、传输和传感能力的极化电路的功能部件。

The project aims to demonstrate quantum state engineering and novel transport of hybrid light–matter particles in semiconductors. These particles, called exciton-polaritons, form macroscopic quantum states extending over microns, and display quantum behaviour on an accessible scale. They inherit ultrafast speeds and large nonlinearities from their light (photon) and matter (exciton) constituents, therefore representing an attractive platform for next-generation optoelectronics. This project is designed to enable us to probe fundamental quantum many-body physics on the macroscopic scale, as well as design and test functional components for polaritonic circuits with information storage, transmission, and sensing capabilities.
