no code implementations27 Feb 2023 Yao Zhang, Hua-Ying Liu, Xiaoyi Liu, Peng Xu, Xiang Dong, Pengfei Fan, Xiaohui Tian, Hua Yu, Dong Pan, Zhijun Yin, Guilu Long, Shi-Ning Zhu, Zhenda Xie

Free-space optical communication (FSO) can achieve fast, secure and license-free communication without need for physical cables, making it a cost-effective, energy-efficient and flexible solution when the fiber connection is unavailable.

A Quantum Algorithm for Solving Linear Differential Equations: Theory and Experiment

2 code implementations12 Jul 2018 Tao Xin, Shijie Wei, Jianlian Cui, Junxiang Xiao, Iñigo Arrazola, Lucas Lamata, Xiangyu Kong, Dawei Lu, Enrique Solano, Guilu Long

We present and experimentally realize a quantum algorithm for efficiently solving the following problem: given an $N\times N$ matrix $\mathcal{M}$, an $N$-dimensional vector $\textbf{\emph{b}}$, and an initial vector $\textbf{\emph{x}}(0)$, obtain a target vector $\textbf{\emph{x}}(t)$ as a function of time $t$ according to the constraint $d\textbf{\emph{x}}(t)/dt=\mathcal{M}\textbf{\emph{x}}(t)+\textbf{\emph{b}}$.
