Micro Lasers for Quantum State Control

许多量子系统使用激光来操纵物质的量子特性。今天，这些激光器本身要比它们控制的量子系统（几毫米——米粒大小）大得多（半米——鞋盒大小）。该项目旨在研究设计紧凑、毫米大小的半导体激光器的可行性，以集成到未来的商业量子处理系统中。激光设计结合了新颖的特性，使激光适合在宽波长范围内进行量子光相互作用，同时避免了昂贵的修改，这将为未来的商业开发创造障碍。

Many quantum systems use laser light to manipulate the quantum properties of matter. Today, these lasers themselves are very much larger (half a metre - shoebox sized) than the quantum systems they control (few millimetres - grain of rice sized). This project is aimed at investigating the feasibility of designing compact, millimetre sized semiconductor lasers to integrate into future commercial quantum processing systems. The laser design incorporates novel features to make the laser light suitable for quantum optical interactions across a wide wavelength range whilst avoiding expensive modifications that would create barriers to future commercial exploitation.
