QIP with trapped electrons in vacuum
Paolo Tombesi, Irene Marzoli · Unicam Scientific Publications (University of Camerino) · 2005
By means of static electric and magnetic fields one can construct scalable traps able to confine many single electrons in vacuum. The ground state and the first excited state of the trapped electron's axial motion together with its spin states store the quantum bits. Selected radio wave or microwave pulses permit to perform any desired logic gate and to implement a fault-tolerant quantum computer.
