Resonant Coulomb interaction of excitonic and charge qubits on quantum dots

The paper considers an algorithm for entangling the states of an exciton qubit on a single quantum dot and a charge qubit on a double quantum dot. The possibility of performing a conditional two-qubit CNOT operation using laser transitions and the Förster effect is analyzed. Estimates of the system parameters are given for which this operation is implemented with a probability close to unity.
