Non-Classical Light from Artificial Atoms

摘要: Publisher Summary This chapter describes single-photon generation with single indium phosphide (InP) quantum dots which emit in the visible spectrum around 690 nm. At this wavelength, highest detection efficiencies Si-based photo detectors are currently available makes InP preferable for free-space optical applications. The character of source enables performance fundamental optics experiments, where wave- and particle-aspect light can be observed simultaneously. demonstrates statistics cross-correlations various transitions from multi-excitonic states including biexciton triexciton decays. Multi-photon may find applications cryptography devices since a higher rate photons also enhances maximum transmission information. Therefore, method to perform multiplexing is presented, similar classical technique, but on level. A typical application— BB84 key distribution protocol—was performed demonstrate method.
