Schematic top view of the double quantum dot nanostructure as discussed in Sec. II.
The occupation probability [Eq. (11)] of the quantum state as a function of the amount of decoherence [in units of ]. For is given by Eq. (12b). Parameters used are , , and all .
The probabilities to measure two spin-up electrons and to measure a spin-up and a spin-down electron in the left and right exits, respectively, for times . Parameters used are , [so that and ], , and for the solid (dashed) curves.
Coefficients , , and in Eqs. (26).
Required substitution of indices and coefficients in Eqs. (27) in order to obtain the corresponding coefficients for with .
