An invitation from a semiconductor physicist: Bridging semiconductor photonics and quantum optics

Kolloquium der Abteilung 4

Semiconductor quantum dots (QDs) based on

III-V materials were discovered in year 1993.

They are expected to bring a paradigm shift to

the researches on quantum communication,

computation and metrology with photons. 24

years has passed and there were tremendous

efforts from the community. However, the QD

based sources are to date still not available to

a broader community (e.g. the quantum optics

community). A number of critical challenges

need to be solved before we can bridge the

gap between different communities.

Luckily, there have been significant progresses

in the last few years. Here I invite you to this

talk and discussion. I will firstly review our

recent efforts towards the development of a

near-ideal entangled photon source based

on semiconductors. Then, the talk will be

concluded with a glimpse of the possible

applications of semiconductor photonics in

advanced quantum optics studies (e.g. in

quantum metrology). Most importantly, the

main goal of this talk is to engage you in

a discussion on how the synergy of two

communities leads to more visible researches

in the coming quantum flagship.
