Description/Info: In this Rapid Communication we propose to use GaN-based quantum dots as building blocks for solid-state quantum-computing devices. The existence of a strong built-in electric field induced by the spontaneous polarization and by the piezoelectricity is exploited to generate entangled few-exciton states in coupled quantum dots without resorting to external fields. More specifically, we shall show how the built-in field induces intrinsic exciton-exciton coupling, which can be used to realize basic quantum information processing on a sub-picosecond time scale

This field present the citation number present on Scopus and Web of science databases e links to the reote records. Also Google Scholar link is present.

There may be discrepancies with respect to the data in databases for the following reasons :

  • Differences from fields (title, year,...) in UGOV and those in the databases.
  • The PORTO citations are extracted monthly. That in the db is in real time
  • Il numero di citazioni per WoS non tiene conto delle citazioni dei Proceedings, in quanto i dati forniti sono calcolati solo sulla base delle collezioni in abbanonamento e il Politcnico di torino non è abbonato al Proceedings Citation Index
