摘      要：Semiconductor quantum dots are leading candidates for the on-demand generation of single photons and entangled photon *** photon quality and indistinguishability of photons from different sources are critical for quantum information *** inability to grow perfectly identical quantum dots with ideal optical properties necessitates the application of post-growth tuning techniques via ***,electric,magnetic or strain *** this review,we summarize the state-of-the-art and highlight the advantages of strain tunable non-classical photon sources based on epitaxial quantum *** piezoelectric crystals like PMN-PT,the wavelength of single photons and entangled photon pairs emitted by InGaAs/GaAs quantum dots can be tuned *** with quantum light-emitting diodes simultaneously allows for electrical triggering and the tuning of wavelength or exciton fine *** from light hole exciton can be tuned,and quantum dot containing nanostructure such as nanowires have been *** ensure the indistinguishability of photons from distant emitters,the wavelength drift caused by piezo creep can be compensated by frequency feedback,which is verified by two-photon interference with photons from two stabilized ***,strain tuning proves to be a flexible and reliable tool for the development of scalable quantum dots-based non-classical photon sources.
