We demonstrate with accurate scattering calculations that a system constituted by a single quantum emitter (a semiconductor quantum dot) placed in the gap between two metallic nanoparticles can display the vacuum Rabi splitting. The largest dimension of the investigated system is only 36 nm. This nonperturbative regime is highly desirable for many possible applications in quantum information processing or schemes for controlling individual photons. Along this road, it will be possible to implement scalable photonic quantum computation without renouncing to the nanometric size of the classical logic gates of the present most compact electronic technology.
我们通过精确的散射计算证明,由放置在两个金属纳米颗粒之间的单个量子发射器(半导体量子点)组成的系统可以显示真空拉比分裂。所研究系统的最大尺寸仅为 36nm。对于量子信息处理或控制单个光子的方案中的许多可能应用,这种非微扰模式是非常理想的。沿着这条道路,有可能在不放弃目前最紧凑的电子技术的经典逻辑门的纳米尺寸的情况下,实现可扩展的光子量子计算。
