title = "Coupling of two localized magnetic moments and its detection",
abstract = "We present results of the theoretical analysis of a device consisting of two quantum point contacts (QPCs) biased close to their pinch-off conditions, so that a local magnetic moment (LMM) is formed in each of them. Another quantum wire, running in parallel to the QPCs, serves as a detector of the states of the two LMMs. Employing the approach of our earlier theory [V. Puller et al., arXiv: cond-mat/0405705] we examine the sensitivity of the linear conductance of the wire to the states of the pair of LMMs. We show that the conductance of this wire exhibits a peak only when the LMMs are in the triplet state, confirming the potential of such a device for quantum computation.",
