... of the SOI have been confirmed by experiments,42–44 the spinprojective properties still require experimental testing. In this paper, we show that single-wall CNT cross-junctions as shown in Fig. 1 are attractive candidates for further experimental progress for both spin-resolved transport and the de ...

Optical control and decoherence of spin qubits in quantum dots P. M
... subspace spanned by |0〉 and |1〉 remains in the subspace spanned by the singleelectron states |0〉, |1〉 and |2〉 (in a trapped state [17]). Thus, the trion state is never occupied, which eliminates the errors due to its finite lifetime. In Sec. 5, we will see that the procedure may be performed in such ...
