Single-shot readout of electron spin states in a quantum dot using spin-dependent tunnel rates
R. Hanson, L. H. Willems van Beveren, I. T. Vink +5
We present a method for reading out the spin state of electrons in a quantum dot that is robust against charge noise and can be used even when the electron temperature exceeds the…
Single-shot read-out of an individual electron spin in a quantum dot
J. M. Elzerman, R. Hanson, L. H. Willems van Beveren +3
Spin is a fundamental property of all elementary particles. Classically it can be viewed as a tiny magnetic moment, but a measurement of an electron spin along the direction of an…
Determination of the tunnel rates through a few-electron quantum dot
R. Hanson, I. T. Vink, D. P. DiVincenzo +4
We demonstrate how rate equations can be employed to find analytical expressions for the sequential tunneling current through a quantum dot as a function of the tunnel rates, for a…
Real-time detection of single electron tunneling using a quantum point contact
L. M. K. Vandersypen, J. M. Elzerman, R. N. Schouten +3
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 capacitivel…
NMR Techniques for Quantum Control and Computation
Lieven M. K. Vandersypen, Isaac L. Chuang
Fifty years of developments in nuclear magnetic resonance (NMR) have resulted in an unrivaled degree of control of the dynamics of coupled two-level quantum systems. This coherent…
