Abstract:
Researchers from the University of Basel in Switzerland and the University of Pittsburgh have come up with a candidate qubit made from groups of electrons rather than harder-to-control single electrons. The researchers have shown that as long as a spin cluster is made up of odd numbers of electrons it can behave like a single electron, according to the Florian Meier, a researcher at the University of Basel. The method can potentially produce qubits that are relatively easy to control.
