Effect of Coulomb Interaction on GaAs Quantum Computer Performance

Interaction between the quantum bits strongly limits quantum computer performance while using large quantum registers. We investigated influence of such interaction for recently proposed quantum computer based on GaAs quantum dots with built-in barrier. Our results show that such interaction could greatly reduce computational fidelity.
