Query: Detection of a charged two-level system by using the Kondo and the
  Fano-Kondo effects in quantum dots   The Kondo effect and the Fano-Kondo effect are important phenomena that have
been observed in quantum dots (QDs). We theoretically investigate the transport
properties of a coupled QD system in order to study the possibility of
detecting a qubit state from the modulation of the conductance peak in the
Kondo effect and the dip in the Fano-Kondo effect. We show that the peak and
dip of the conductance are both shifted depending on the energy-level of the
qubit. In particular, we find that we can estimate the optimal point and
tunneling coupling between the |0> and |1> states of the qubit by measuring the
shift of the positions of the conductance peak and dip, as functions of the
applied gate voltage on the qubit and the distance between the qubit and the
detector.
