Both the charge and the spin of an electron in a QD have been considered as qubit candidates. However, two recent papers show that an even better bet could be the absence of one electron (known as ...
Indeed there is, in addition to the obvious ways to manipulate the spin using magnetic fields, an indirect effect on the electron spin from externally applied electric fields, due to the so-called ...
One of the most powerful tools for studying these waves is time-resolved electron microscopy ... the team investigated a specific spin texture known as a meron pair. A meron is a topological ...
