Figure 4From: One-qubit quantum gates in a circular graphene quantum dot: genetic algorithm approachTime evolution of probability density and pseudospin current for the quantum gate σ x and σ y operation. Time evolution of density and current probability due to the effect of the produced quantum gate σx in the left side and σy in the right side, initial state |Ψ0〉 = |0〉 (Figure 1b).Back to article page
