摘要：

A method for reading out the states of an electron in a single measurement for the development of quantum computing, is described. Delft researchers, in an experiment, have determined whether the pair is in singlet state, whereby the two electron spins point in opposite directions. For this purpose, an electron was added to a quantum dot that already contained one electron by applying a voltage pulse to one of the confining gates. The voltage pulse ends about a millisecond later, allowing one electron to escape from the quantum dot.
