Abstract

Using high-spatial resolution scanning magneto-photoluminescence (PL) of InP/GaInP2 quantum dots (QDs) we revealed a formation of fractionally charged magneto-electron (em) – a localized particle, consisting of a few magnetic flux quanta self-generated by a single electron. It can be considered as a single particle version of composite fermions involved in fractional quantum Hall effect (FQHE) and used for realization of topological quantum computing schemes. Using six electron QD we demonstrate optically induced pairing (fusion) and interchange (braiding) of ems, which are the necessary steps in the operation of the topological quantum gate.

Abstract

We used the measurements of the photo-luminescence spectra vs photon pumping and Coulomb blockade charge tuning together with Kelvin probe microscopy to study piezo-electric fields in self-organized InP/GaInP2 quantum dots (QDs) having a strong Wigner localization regime. These exciton/electron state-filling measurements together with the surface potential imaging and the band structure calculations demonstrate a piezo-electric doping and type-I optical transitions induced in these dots by an atomic ordering (AO) of GaInP2. Our results clarify a critical role of AO in the formation of natural Wigner and anyon molecules and represent an important step for realization of the topological quantum gates using these QDs.
