Micro Lasers for Quantum State Control

许多量子系统使用激光来操纵物质的量子性质。今天，这些激光器本身比它们控制的量子系统(几毫米米粒大小)要大得多(半米鞋盒大小)。该项目旨在研究设计紧凑型毫米尺寸半导体激光器以集成到未来商业量子处理系统的可行性。激光器设计采用了新颖的功能，使激光适合于宽波长范围的量子光学相互作用，同时避免了昂贵的修改，这可能会对未来的商业开发造成障碍。

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.
