GQDs were also found to have four quantum states at a given energy level, unlike semiconductor quantum dots, which have only two.These additional quantum states, according to researchers, could make GQDs beneficial for quantum computing.
In GQDs, four localized electron states with the same energy allow for switching between different quantum states to store information and these electrons can preserve arbitrary superpositions that are ideal properties for quantum computers. In addition, GQDs can be used for quantum information application
