Abstract
Disclosed is a method for determining a charge-state boundary of a quantum dot, a multi-dot device, or an array of quantum dots, including the steps of defining an initial point inside a charge state of a quantum dot having a charge-state boundary, ramping gate voltages from the initial point thereby creating a plurality of rays in gate voltage space, creating a time stamp when each of the rays leave the charge-state/cross the charge-state boundary, and constructing the boundary of the charge state by correlating each ray in gate voltage space with the associated time stamp.
