Meunier, T. (author), Vink, I.T. (author), Willems van Beveren, L.H. (author), Koppens, F.H.L. (author), Tranitz, H.P. (author), Wegscheider, W. (author), Kouwenhoven, L.P. (author), Vandersypen, L.M.K. (author)We propose and implement a nondestructive measurement that distinguishes between two-electron spin states in a quantum dot. In contrast to earlier experiments with quantum dots, the spins are left behind in the state corresponding to the measurement outcome. By measuring the spin states twice within a time shorter than the relaxation time T1,...journal article 2006

(author)We observe individual tunnel events of a single electron between a quantum dot and a reservoir, using a nearby quantum point contact (QPC) as a charge meter. The QPC is capacitively coupled to the dot, and the QPC conductance changes by about 1% if the number of electrons on the dot changes by one. The QPC is voltage biased and the current is...journal article 2004

Elzerman, J.M. (author), Hanson, R. (author), Willems van Beveren, L.H. (author), Vandersypen, L.M.K. (author), Kouwenhoven, L.P. (author)We demonstrate a method for measuring the discrete energy spectrum of a quantum dot connected very weakly to a single lead. A train of voltage pulses applied to a metal gate induces tunneling of electrons between the quantum dot and a reservoir. The effective tunnel rate depends on the number and nature of the energy levels in the dot made...journal article 2004
