Abstract

We studied the effect of magnetic field and interdot distance on the exchange interaction in two systems of double qubits, one made of Si and the other made of GaAs. We found that the effect is the same for both systems, but the exchange value for Si qubits is smaller due to the larger effective mass of electrons. This study provides insights into the exchange interaction, which is essential for the development of quantum computers.
