Generation of three-qubit entangled states using coupled multi-quantum dots

摘要

We discuss a mechanism for generating a maximum entangled state (GHZ) in acoupled quantum dots system, based on analytical techniques. The reliablegeneration of such states is crucial for implementing solid-state based quantuminformation schemes. The signature originates from a remarkably weak fieldpulse or a far off-resonance effects which could be implemented usingtechnology that is currently being developed. The results are illustrated withan application to a specific wide-gap semiconductor quantum dots system, likeZinc Selenide (ZnSe) based quantum dots.
