量子频率处理器

Quantum Frequency Processor

A fully integrated silicon photonic device that monolithically combines a microresonator-based biphoton quantum frequency comb source, a pump-rejection filter, high-speed phase modulators, and a four-channel, line-by-line pulse shaper to generate, manipulate, and measure high-dimensional frequency-bin entangled states on a single chip. / 一种完全集成的硅光子器件,单片集成了基于微谐振器的双光子量子频率梳源、泵浦抑制滤波器、高速相位调制器和四通道逐线脉冲整形器,用于在单片上生成、操纵和测量高维频率分量子纠缠态。
