N2 - Recently, the investigations on the coherent tunnelling in a coupled quantum-dot (QD) system have carried out both experimentally (Blick et al., 1998, and Oosterkamp et al., 1998), and theoretically (Tsukada et al., 1997, and Wu et al., 2000). However, all of these studies did not take the influence of the measurement into account. It is well known that measurement itself will certainly induce dephasing. This effect was studied (Aleiner et at., 1997, Levinson, 1997, and E. Buks et al., 1998) in detail. Also, Gurvitz et al. (1996, 1997) derived modified rate equations and studied the dephasing effect induced by measuring the electron state in a coupled QD system via a quantum point contact.
