【摘要]】

Boson sampling is considered as a strong candidate to demonstrate quantum computational supremacy over classical computers [1]. High efficiency single photon source is a crucial resource for this appealing goal [2]. Here in first part of this talk, I will go through the recent progresses on semiconductor based single photon sources which made on-demand, high purity, and indistinguishable fulfilled simultaneously [3, 4]. Then in the second part, I will show two approaches that we realized Boson sampling in temporal [5] and spatial freedoms [6], and give some discussions on the future directions.

【报告人简介】

 Dr. Yu He obtained his PhD degree in 2016 in University of Science and Technology of China, under the supervision of Prof. Chao-Yang Lu and Prof. Jian-Wei Pan. His PhD work is focused on single-photon sources base on InGaAs self-assembled quantum dots, main results including high performance single photon sources, Boson sampling and state transfer in a quantum dot. Afterwards, he moved to Michelle Y. Simmons’s group as a postdoctoral research associate in University of New South Wales, Sydney. The new field is precision placed P donor silicon quantum computing.
