Abstract [en]

It is known that a two-spin system with four energy levels can be used to realize a two-qubit quantum gate. A feasible realization of quantum gates should rely on stable quantum mechanical states. An example of such states are edge states which arise around regions with high potential in a strong magnetic field. In this paper we show that certain edge states around a pair of antidots may be suitable for quantum gate implementation.
