Abstract
The physical basis of the method of implementing quantum logical operations in a continuous microwave field in a system of two electrons with different g-factors and a constant exchange interaction is developed. A small variable additive Δ B ( t ) to the magnetic field is proposed as a control action. It is obtained that a simple functional dependence Δ B ( t ), based on harmonic functions, allows us to perform elementary quantum logical operations and their sequences. This method is adapted to the experimental conditions.
