Constructing mehod of 2-EPP with different quantum error correcting
... In this paper, we proposed a method to construct a 2EPP which consists of different quantum error correcting codes and by simulations investigated the performance of the 2-EPPs for a phase-damping channel. The proposed protocol showed improved fidelity and purification rate compared with an EPP from a ...

It shows that the position of ε2 with respect to the Fermi level determines the shape of the Fano conductance peaks through ε1 and Fano parameter q ∝ –Γ2/ε2. A similar situation has been encountered in the case of a large dot with strongl ...
